### How do you derive efficiency formula from heat rate for stem turbine?

Efficiency formula for a steam turbine is typically derived by dividing the electrical power output by the heat energy input. The heat rate of the steam turbine represents the amount of heat energy required per unit of electrical power generated, and by rearranging the equation, we can derive the efficiency formula as the reciprocal of the heat rate.

### What is the heat formula?

The formula for calculating heat is Q = mcΔT, where Q represents the amount of heat transferred, m is the mass of the object, c is the specific heat capacity of the object, and ΔT is the change in temperature.

### What is the Formula for calculating heat transfer by convection?

The formula for calculating heat transfer by convection is: Q = h * A * ΔT, where Q is the heat transfer rate, h is the convection heat transfer coefficient, A is the surface area, and ΔT is the temperature difference between the surface and the surrounding fluid.

### Choose the correct formula determing specific?

The formula for calculating specific heat capacity (c) is: q = mcΔT, where q represents the heat transferred, m is the mass of the material, ΔT is the change in temperature, and c is the specific heat capacity.

### What type of energy does the steam in a steam turbine have?

It is heat energy. The turbine turns heat energy into mechanical energy.

### Why would you not heat the steam coming out of turbine and feedback to turbine?

becouse this steam is use repetdly for the turbine

### What is the use of latent heat in vaporization?

Calculating heat absorbed or released when any gas / liquid transformation takes place. I'm not an engineer, but I would imagine these calculations are performed in designing steam plants to make electricity. Water must be boiled, the steam runs thru a steam turbine, then it is condensed into water and is recycled ... boiledto steam ... thru turbine ... condensed etc.

### How is hfusion used to calculate the energy needed to mention a mass of a solid?

The formula for calculating the energy needed to melt a mass of a solid is Heat energy = mass x specific heat capacity x ΔT + mass x heat of fusion. This formula includes the specific heat capacity of the material, the change in temperature, and the heat of fusion required to melt the material.

### What is a kind of engine that uses water steam or heat that starts with tur?

The word is "turbine".

### Why vacuum is created in condenser on steam turbine?

Firstly, vacuum is being created in turbine exhaust and condenser rather than being required. It is created to reduce the back-pressures and to improve the turbine efficiency. Also, with vacuum the designers can design large size last stage blades of LP turbine for maximizing the turbine output.

### Heat rate of gas turbine?

The heat rate of a gas turbine using petroleum is 13,622. On the other hand, gas turbines that use natural gas produce a heat rate of 11,499.
