1) Saturated liquid water at a pressure of 10 kPa is sent to a steam boiler with a pressure of 4MPa with a reversible adiabatic pump and heated up to 500oC at constant pressure in the boiler. The mass flow of the steam is 4.2 kg / s. Transactions are carried out continuously.

a) Show the processes on the T-v or T-s diagram with saturated vapor and liquid curves.

b) Calculate the required pump power

c) Calculate the amount of heat spent per unit time in the boiler

Saturated water vapor at 1000 kPa is throttled to 100 kPa. The velocity of the steam remains constant through the process. Determine the exit temperature of the water vapor. I know this is already awnsered in a solution for 1st edition but can someone help me understand what they do and how they picked the numbers they did from some table to get the exit temperature?

Rankine cycle operates on boiler pressure 15 MPa and condenser pressure of 30 kPa. Superheated steam enters the high-pressure turbine at 450°C. The high-pressure turbine expands the steam and enters the re-heater at 2.5 MPa. The steam is reheated until temperature reaches 450°C before being expanded in low-pressure turbine to condenser pressure of 30 kPa. Assume the isentropic efficiency of the low-pressure and high-pressure turbines are 94% and 89% respectively, and pump is working isentropically. Neglect the change in kinetic...

Liquid water at 15 ℃ is heated by mixing it with saturated steam at the same pressure. Liquid water enters a chamber at a rate of 4.3 kg/s and saturated steam enters at a rate of 0.17 kg/s. The mixture leaves the mixing chamber as a saturated liquid at 40℃. If the surroundings are at 15℃, determine (a) the temperature of the saturated steam entering the chamber, (b) the exergy destruction during this mixing process, and (c) the second-law efficiency...

Steam produced in a boiler is frequently “wet”—that is, it is a mist composed of saturated water vapor and entrained liquid droplets. The quality of a wet steam is defined as the fraction of the mixture by mass that is vapor. A wet steam at a pressure of 5.0 bar with a quality of 0.85 is isothermally “dried” by evaporating the entrained liquid. The flow rate of the dried steam is 52.5 m3/h. (a) Use the steam tables to determine...

A steam boiler of volume 2.3 m3 initially contained 1.7 m3 liquid water in equilibrium with 0.6 m3 of vapour at 100 kPa. The boiler is heated keeping the inlet and discharge valves closed. The relief valve is set to lift when the pressure in the boiler reaches 5500 kPa. Determine the amount of heat supplied to the contents in the boiler before the relief valve lifts.
