Answer:

- Work done is 2.39 kJ

- heat transfer is 20.23 kJ/kg

Explanation:    

Given the data in the question;

First we obtain for specific volumes and specific enthalpy from "Table Properties Refrigerant 134a;

Specific Volume v₁ =  0.02547 m³/kg

Specific enthalpy u₁ = 243.78 kJ/kg

Specific Volume V₂ = 0.02846 m³/kg

Specific enthalpy u₂ = 261.62 kJ/kg

p = 8 bar = 800 kPa

Any changes in kinetic and potential energy are negligible.

So we determine the work done by using the equation at constant pressure

]Work done W = p( v₂ - v₁ )

we substitute

W = 800 kPa( 0.02846 m³/kg - 0.02547 m³/kg )

W = 800 kPa( 0.00299 m³/kg )

W = 2.39 kJ

Therefore, Work done is 2.39 kJ

Heat transfer;

using equation at constant pressure

Heat transfer Q = W + ( u₂ - u₁ )

so we substitute

Q = 2.392 kJ + ( 261.62 kJ/kg - 243.78 kJ/kg )

Q = 2.392 kJ +  17.84 kJ/kg )

Q = 20.23 kJ/kg

Therefore, heat transfer is 20.23 kJ/kg

Your answer will be A.

If you lower the Air Pressure your Object will Float Down ward. The Air Pressure allows it to Fly.

The pressure field created by faster air movement over an airfoil is; A:  higher

When the air hits the front of the wing, the air will flow in a steeper curve upward, than the bottom wing flow which will lead to the creation of a vacuum on top of the wing that pulls more air towards the top of the wing.

Finally, this air above does the same thing but it will move faster as a result of the vacuum pulling it in, and as such the vacuum now lifts the wing. Thus, Faster air movement over an airfoil creates a higher pressure field.

Gauge Pressure = 408.3 KPa

Explanation:

The pressure inside the pipe can be given in terms of the elevation, by the following formula:

P = ρgΔz

where,

P = Absolute Pressure = ?

ρ = Density of Water = 1000 kg/m³

g = acceleration due to gravity = 9.8 m/s²

Δz = elevation = 52 m

Therefore,

P = (1000 kg/m³)(9.8 m/s²)(52 m)

P = 509.6 KPa

Now, for gauge pressure:

Gauge Pressure = P - Atmospheric Pressure

Gauge Pressure = 509.6 KPa - 101.3 KPa

Gauge Pressure = 408.3 KPa

Pattern is melted out for recycling before pouring is called the lost-wax casting.

In the manufacturing process known as casting, a liquid substance is often poured into a mold that has a hollow chamber in the desired shape before being left to solidify. Casting is another name for the solidified component that is released from the mold at the end of the process. By pouring molten metal into a mold, allowing it to solidify, and then cooling it to room temperature, the casting process is a manufacturing technique that creates metal pieces in the required shape. No matter how big the parts are, it can produce intricate and complex parts. Expendable and non-expendable casting are the two basic categories into which the modern casting process is split. The mold material—such as sand or metal—and the pouring technique—such as gravity, vacuum—further break it down.

The two primary types of fire suppression operations are direct attack and indirect attack, with direct attack targeting the flames and indirect attack targeting the fire's fuel and heat sources.

The two primary types of fire suppression operations are direct attack and indirect attack.

The direct attack involves directly targeting the flames with an extinguishing agent, such as water or foam, in order to extinguish the fire at its source. This is typically the most effective method, as it directly reduces the heat and removes the fuel source. However, it can also be dangerous if the fire is too intense or if firefighters are unable to get close enough to the flames.

An indirect attack, on the other hand, involves targeting the fire's fuel and heat sources instead of the flames themselves. This can involve establishing fire breaks, back burning, or using a fire to slow the fire's spread. This method is typically used when a direct attack is not possible, such as when the fire is too large or in a location that is difficult to access.

It's important to note that these two methods are often used in combination, depending on the size, location, and intensity of the fire. Firefighters will assess the situation and choose the best course of action to safely and effectively extinguish the fire.

Overall, fire suppression operations require careful planning, coordination, and execution to ensure the safety of both firefighters and civilians.

Conducting a detailed cost analysis and consulting with local authorities and experts would be necessary to accurately determine the most cost-effective land zone for building an electricity transmission line in a specific location.Here is a rough ranking, from the cheapest to relatively more expensive land zones for building an electricity transmission line:

1. Rural: Rural areas typically have lower land costs due to their remote locations and limited development. These areas are often characterized by large stretches of open land with fewer zoning restrictions, making them potentially more affordable for transmission line construction.

2. Industrial: Industrial areas, particularly those located outside urban centers, may offer relatively affordable land for transmission line construction. These zones are typically designated for industrial activities and may have existing infrastructure and utility connections that can reduce costs.

3. Rural Residential: Rural residential areas are residential zones located in rural or semi-rural settings. While these areas may have a mix of residential and agricultural land uses, they could still be less expensive compared to urban or suburban residential zones.

4. Local Activity Zone (LAZ) - Commercial: Local Activity Zones are designated areas for commercial activities, such as small businesses, retail outlets, and offices. While they may be more developed and have higher land costs compared to rural or industrial areas, they can still offer relatively affordable options for transmission line construction.

5. Large Scale Retailing (LSR) - Commercial: Large Scale Retailing zones are designated for large retail outlets and shopping centers. These areas are more likely to be located in or near urban centers and may have higher land costs compared to the previous categories.

6. Central Activity-Commercial: Central Activity Zones are typically located in urban centers and consist of commercial, retail, and office spaces. These areas tend to have high land costs due to their prime locations and proximity to urban amenities.

7. Campus: Campus zones are designated for educational institutions, universities, and schools. These zones are typically located in urban or suburban areas and may have higher land costs due to their desirable locations and proximity to amenities.

8. Port: Port areas are designated for maritime activities, including shipping, transportation, and logistics. While port areas can vary widely in cost depending on location and demand, they often have higher land costs due to their strategic positions and proximity to transportation infrastructure.

9. Residential: Residential zones within urban or suburban areas tend to have the highest land costs due to their desirability and proximity to amenities, services, and transportation networks.

10. Ocean: Land zones adjacent to the ocean or waterfront areas are typically highly sought after and expensive due to their scenic views, recreational opportunities, and potential environmental considerations.

It's important to note that the specific cost and availability of land within each zone can vary significantly based on regional factors, local market conditions, and other site-specific considerations.

Heat is transferred by conduction when a jar of baby food is heated by submerging it in hot water.

The transfer of heat energy by conduction occurs when two things come into direct touch. Since the jar of baby food and the hot water are in direct contact in this instance, heat can be transferred from the water to the food.

The jar of baby food is the "cold" object because it has a lower temperature, while the hot water is the "hot" object since it has a higher temperature.

Heat is transferred from the hot water to the jar and then to the baby food when the two things come in contact.

Heat transmission through conduction is used to heat the baby food jar in hot water. Until thermal equilibrium is attained, heat is transported from the hot water to the jar and then to the food.

Thus, the baby food's and the jar's specific heat capacity have an impact on how quickly heat is absorbed and how quickly the temperature rises.
