Heat and Mass Transfer Practice Exam Questions Flashcards
What happens to the local heat-transfer rate and the thermal boundary-layer thickness as you go further down the plate? Explain. The thermal boundary later becomes thicker as you go down the plate as more heat is entrained. This causes the temperature gradient to decrease which decreases the local heat transfer rate.
MAE 423 – HEAT AND MASS TRANSFER EXAM 3 Practice Questions Name: _____ You are allowed three sheets of notes. 1. A 20 mm diameter spherical ice cube (at 0° C) is placed in a drink (mostly water) which is at room temperature (20° C). What is the heat transfer rate if the ice cube is fully immersed without any shaking or stirring?

Using both the LMTD and NTU methods, determine the required heat transfer area. What is the steam condensation rate? Assume correction factor F = 1. Properties: Steam (1 bar, saturated): Th = 380 K, hfg = 2238 × 103 J/kg⋅K; Water (T = 316 K): cp = 4179 J/kg⋅K, μ = 725 × 10 -6 N⋅s/m 2 , k = 0 W/m⋅K, Pr = 4.
