Please take time but solve for me all handwriting or text all parts please
![Problem 2
The figure below shows the integration of devices used in a steam power plant with a reheat
heat exchanger, and most of their operational data. The reheat heat exchanger is used to
supply heat to the steam that leaves Turbine 1 before it enters Turbine 2 by using "hot"
combustion gases. Combustion gases may be modeled as air and the devices may be assumed
to be perfectly insulated. Starting with the general form for the mass and energy conservation
expressions for a control volume, please answer the following questions.
Note: all property values used to solve this problem must be obtained from the thermodynamic
tables in your textbook, please list the table number used.
a. Compute the mass flow rate of steam passing through Turbine 1, in kg/s. List the
assumptions you used.
b. Estimate the temperature of the steam when it exits the heat exchanger, in °C. List the
assumptions you used. Use the method of variable specific heats for the hot combustion
gases stream modeled as air.
c. On a single T-v diagram represent the processes for the steam. Identify the states using
the same numbers given in the figure below. Include the saturation lines and relevant
property values associated to each state.
d. Compute the power produced by Turbine 2, in kW.
