Aheat exchanger is used to transfer heat from a steam stream to a chlorine gas stream. 100 kg of steam at 1 bar and 350°c enters the heat exchanger and leaves the exchanger as saturated steam at 1 bar. chlorine gas enters the exchanger at 1 bar and 28.0°c and leaves the exchanger at 140.0°c. assume the heat exchanger is adiabatic. what is the specific enthalpy of the inlet steam stream? (use liquid water at 0.01°c as a reference state.)

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
