A heat exchanger operates at steady state, and both flows through the exchanger are isobaric.

Water flows through one side of the heat exchanger at 20 bar. The inlet temperature of the water is 280 Celsius. The outlet is saturated liquid. The mass flow rate of water is 2.0 kg/s.

Air flows through the other side of the heat exchanger at 1 bar. The inlet temperature of the air is 300 K. The mass flow rate of air is 9.0 kg/s.

Determine the outlet enthalpy of the air, in kJ/kg.

A)759.7

B) 859.7

C)812.2

D)776.2

Consider a power plant with water as the working fluid that operates on an ideal rankine cycle. it has a net power output of 45mw. superheated steam enters the turbine at 7mpa and 500°c (h=3411.4 kj/kg; s=6.8 kj/kg k) and is cooled in the condenser at a pressure of 10 kpa by running cooling water from a lake through the tubes of the condenser at a rate of 2000 kg/s. (a) show the cycle on a t-s diagram (a right schematic is fine - you do not need to calculate the temperatures at each point); (b)-determine the work done by the turbine and the pump in kj/kg; (c)-the mass flow rate of water used by the power plant; (d)-the thermal efficiency of the cycle; (e)-the temperature rise of the cooling water. assume the cooling water is incompressible with cp 4.18 kj/kg°c.

Areheat rankine cycle operates with water as the working fluid. steam enters the first turbine at 8 mpa and 450°c and exits at 0.8 mpa. it is then reheated to 400°c before entering the second turbine, where it exits at 10 kpa. if the amount of work into the pump is 8.04 kj/kg and the net work per cycle produced is 1410.25 kj/kg, determine the thermal efficiency of the cycle.
