Saturated liquid water flows through a pipe and is heated by a pump that vaporizes the water. The pipe has water flowing at a rate of 50 grams per second and at a pressure of 180 kPa. The pump receives heat from a reservoir at 10°C and supposedly requires 32 kW of power. a. Find the heat from pump required to vaporize the water in the pipe b. Find the temperature of the water inside the pipe. c. Find the...
A mass of 0.2 kg of saturated liquid water is completely vaporized at a constant pressure of 100 kPa. Determine; (a) The volume change. (b) The amount of heat added to the water. (c) Show the process on a (p-v) diagram.
Saturated liquid water at 10 kPa leaves the condenser of a steam power plant and is pumped to the boiler pressure of 5 MPa. Calculate the work for an isentropic pumping process in kJ/kg.
The following diagram illustrates a simple steam power plant. A
10kg/s flow of liquid water at T1=25°C enters the pump at a
pressure of P1=100kPa and is then pumped to a pressure of P2=2MPa.
The boiler then heats the water at constant pressure to produce
superheated vapour at T3=450°C. The steam is then expanded in the
turbine to a final pressure of P4=100kPa. The turbine and pump are
well insulated and may be considered reversible.
a) Find the turbine exit...
