Friends I have a doubt in the following matter:
We have a hot water generator of capacity 1million kCal/hr and 4 kg/cm2 @ 140 C. The circulation is closed loop, means hot water is circulating from generator to process and back to generator and so... Flow is created by a circulation pump of capacity 42 m3/hr.
My problem is the pressure drop between supply and is return is almost zero (0.1 or .2).
My process contains 15 heating coils and 8 shell and tube heat exchangers. We are expecting a pressure drop of 1.5 or 2.
Is in closed loop continuous pumping system pressure drop will not be evident?
Pls help
