Question: Steam at atmospheric pressure condenses on the outside of an l = 5 m long tube of diameter D = 0.3 m. Water at temperature Ti = 20 °C flows, with a mass flow rate of 02 kg/s, inside the tube. Find the mass flow rate of the condensing steam. For steam: p = 1 atm, Ti = 100 °C, hfg = 2.257 kJ/kg.
Determine the factor by which the resistivity given in Ω · m should be multiplied by in order to obtain the resistivity in Ω · cmil/ft.
