Heat Transfer Boiling Example Problem

Heat Transfer Boiling Example Problem

Nucleate Boiling example problem includes how to find critical heat flux, rate of evaporation, and surface temperature at the critical heat flux. You will also learn about the boiling curve, or boiling regimes curve. Once past the critical heat flux temperature, very different results are obtained if the system temperature increases (transition to film boiling) vs if the system heat flux increases (burnout). Along the way evaporation rate is solved using latent heat of vaporization, hfg. Problem Statement: In a gas-fired boiler, water is boiled at 150° C by hot gases flowing through 25-m-long, 5-cm-outer-diameter mechanically polished stainless steel pipes submerged in water.
