The condenser of a large steam power plant is a heat exchanger in which steam is condensed to liquid water. Assume the condenser to be a parallel flow shell-and-tube heat exchanger consisting of a single shell and 10,000 tubes, each executing two passes. The tubes are of thin wall construction with D = 30 mm and the steam condenses on their outer surface. The heat transfer rate that must be effected by the exchanger is Q = 2 × 10^9...

Water is used to cool R-134a in the condenser of a heat exchanger. The refrigerant enters the counter-flow heat exchanger at 800 kPa, 80 0C and a mass flow rate of 2 kg/s. The refrigerant exits as a saturated liquid. Cooling water enters the condenser at 500 kPa and 18 0C and leaves the condenser at 30 0C. Determine the necessary mass flow rate of water. Each fluid is assumed to flow at constant pressure.

Liquid water at 24 ºC is fed to a boiler operating at 10 bars and is converted at constant pressure to saturated steam.  The steam is produced at a steady state flow rate of 15,000 m3/hr.  Assume that the kinetic energy of the liquid entering the boiler is negligible, and that the steam is discharged from the boiler through a 15 cm diameter pipe.   What is the temperature of the saturated steam (ºC)? Calculate ∆Ĥ (in units of kJ/kg) for this process....

Question 4 Saturated steam at 227°C is used in a heat exchanger to preheat a reactor feed stream. (a) If the condensate (saturated liquid) is removed from the heat exchanger at 152°C and the flow rate is 1000 kg/h, how much heat (kJ) is transferred from the steam to heat up the reactor feed stream in one hour? (b) How much additional steam would be required if the condensate is removed at 227°C, instead of 152°C, for the same exit...

A power plant using an ideal Rankine power generation cycle operates at an efficiency of 55% with a flowrate of steam of 2 kg/s.  Heat is supplied to the boiler of 2500 kJ/kg. The pump takes in saturated liquid water at 100 kPa and has an exit pressure of 10 MPa.  Determine: the exit temperature of the pump (oC)  (3 pts) the work of the turbine (kW) (3 pts) the heat exhausted from the condenser (kJ/s) (3 pts)

A condenser is essentially a type of heat exchanger that is used to remove heat from a vapor and convert it to liquid. The picture below shows a condenser that is used in a commercial refrigerator with refrigerant-134a as the working fluid. Water enters the condenser at 18ºC at a rate of 0.25 kg/s and leaves at 26ºC. The refrigerant enters the condenser at 1.2 MPa and 50ºC and leaves at the same pressure but at T=41.3ºC. a) Find the...

A steam power plant operates with a high pressure of 4 MPa and has a boiler exit at 600C recieving heat from 700C reservoir. The ambient air at 20C provides cooling to maintain the water/vapor mixture in the condenser at 60C. All components are ideal (reversible) except the turbine which has an efficientcy 92% of a reversible, isentropic process. other than that the irreversibility of the turbine, the power plant can be considered as a Rankine cycle. Determine the following...

1. You will learn much about heat engine cycles in thermo II (if you take it), but you already have the basic skills needed to perform a rst law analysis of a simple vapor power cycle. This cycle has four basic components: steam turbine, condenser, liquid pump, and boiler, and four as- sociated processes. A speci c case of this cycle has water, in the form of a saturated vapor at 40 kPa, exiting from the turbine and entering the...

A nuclear power plant generates 3000 MW of heat energy from nuclear reactions in the reactor's core. This energy is used to boil water and produce high-pressure steam at 300?C . The steam spins a turbine, which produces 900MW of electric power, then the steam is condensed and the water is cooled to 25?C before starting the cycle again. A) What is the maximum possible thermal efficiency of the power plant? Express your answer using two significant figures. B) Cooling...
