A liquid is heated from 25°¢ to 75°¢ as the fluid moves at 0.2m/see through a thin-walled steal tube. The tube dia is 12.7 mm and som long. The tube is heated with uniform heat flux (= constant). Assume the flow has a fully developed velocity profile and temp profile at inleto; for finid Co= 4000 PK, M= 2x10 E K=0,8 mmk, Pr=10., p=1000 km², v=le k W sec.m 250 fluid Tmi d U₂ 0.2 ↑ =constant case [₂P=7&S ↑ 150= ? 1 # d=127 am Kiom a) find mass Finx in () for Fluid, Rep, and find the applied heat flux: g" (m²) b) find h() at exit; X=10m. c) find the tube surface temp at exit (¹²5₂)
