Short contact time pipe convection
Splet18. dec. 2008 · The rate of heat transferred to the water is simply mass flow rate times the temperature change of the water times the specific heat of the water. Since mass flow rate of the water is indeed a rate, the resulting computation will be in kW (or BTU/sec): (kg/sec)* (Temp change in K)* (kJ/kg-K) = kJ/sec = kW. SpletThe pipe is, as seen above, made of steel with a thermal conductivity of 30 W/m/K. The insulating material has a thermal conductivity of 0.035W/m/K. The pipe is 3.5 m. He …
