Determine the rate of heat removal - mechanics, Mechanical Engineering

Assignment Help:

Determine the rate of heat removal:

Carbon dioxide passing through heat exchanger at rate of 100kg/hr is cooled down from 8000C to 500C. Write down the steady flow energy equation. Assuming that change in pressure, potential, kinetic energies and work interaction are insignificant; determine the rate of heat removal. (Take Cp = 1.08Kj/kg-K) 

Sol: Given that:

mf  = 100Kg/hr = 100/3600 Kg/sec = 1/36 Kg/sec

T1  = 8000C

T2  = 500C

Cp = 1.08Kj/kg-K

Rate of heat removal = Q = ? By Applying SFEE

As change in pressure, kinetic and potential energies and flow work interaction are negligible, that is;

Now
