Water flowing at 5 kg/s and initially at 100 kPa, 20°C is to be delivered as steam at 2000 kPa, 350°C and the same flow rate to some application. The following two-step sequential process is employed to achieve the required delivered steam conditions:Step 1 – adiabatic compression to 2000 kPa, 20°C.Step 2 – constant-pressure heating to 350°C. How much work in kJ/s is needed in Step 1 and Step 2? What is the required heat transfer in kJ/s to accomplish Step 2?

Question

Water flowing at 5 kg/s and initially at 100 kPa, 20°C is to be delivered as steam at 2000 kPa, 350°C and the same flow rate to some application. The following two-step sequential process is employed to achieve the required delivered steam conditions:
Step 1 – adiabatic compression to 2000 kPa, 20°C.
Step 2 – constant-pressure heating to 350°C.

How much work in kJ/s is needed in Step 1 and Step 2? What is the required heat transfer in kJ/s to accomplish Step 2?
