Heat carried by a mass stream calculator

Steam and blowdown heat flows are mass rate times tabulated enthalpy.

Units
qstream=m˙×hq_{\text{stream}} = \dot{m} \times h

Worked example

Given

  • m˙\dot{m} = 1,000 lb/h
  • hh = 1,150 Btu/lb
qstream=1000×1150=1,150,000q_{\text{stream}} = 1000 \times 1150 = 1{,}150{,}000
