Hello, why do I see some people with h5, they immediately equate it with h3? Does it matter if I do interpolation using their temperatures or using h3 as h5?
An ideal Rankine steam cycle modified with two closed feedwater heaters. The power cycle receives 15 kg/s of steam at the high-pressure inlet to the turbine at temperature 600 °C and pressure 5 MPa. The condenser pressure is 20 kPa. The feedwater heater exit states for the boiler feedwater and the condensed steam are the normally assumed ideal states. The fraction of mass extracted at 1500 kPa for the high-pressure closed feedwater heater is 0.16 (a) Sketch the T-s diagram for the ideal cycle. (b) Determine the fraction of mass that is extracted at the 250 kPa for the low pressure closed feedwater heater (c) Determine the net power output and the thermal efficiency of the plant.
Water is the working fluid in vapor power cycle. Saturated liquid enters the boiler at a pressure of 10 MPa, and enters the turbine as saturated vapor. The condenser pressure is 9 kPa. Determine (a) the thermal efficiency, (b) the back work ratio, (c) the heat transfer to the working fluid per unit mass passing through the boiler in kJ/kg and (d) the heat transfer from the working fluid per unit mass passing through the condenser in kJ/kg. (e) What would the thermal efficiency be if the steam entered the turbine at 5 MPa and the condenser pressure were 90 kPa? Please, make answer for this problem, sir
Thank you for making this, it was really helpful!
