Heat transfer
![a) In a methanol production plant, process water at 30°C with a free stream velocity of
0.3 m/s flows over a 1m x1m flat plate. Temperature of flat plate is maintained at
10°C using other stream Freon R134-a which flow at inlet temperature 0°C and outlet
temperate 5°C. Determine the
i. hydrodynamic boundary layer thickness,
ii. thermal boundary layer thickness,
i. local and average values of friction coefficient
iv. local and average heat transfer coefficient
vi. amount of Freon R134-a necessary to maintain the plate temperature
(Cp Freon=1.3338 kJ/kg.K)
b) Consider a concentric annulus of inner diameter D 2.5 cm and outer diameter D. 5
cm length is 6 m, Air (flow inside annulus) at 293 K 800kPa bar is chilled by concurrent
flow of melting ice (flow inside tube). Determine the exit temperatures of dry air if flow
