Develop an expression for the ratio of the rate of heat transfer to water at 40°C from a thin flat strip of width ?D/2 and length L at zero angle of attack and a tube of the same length and diameter D in cross-flow with its axis normal to the water flow in the Reynolds number range between 50 and 1000. Assume both surfaces are at 90°C.
GIVEN
• Water flowing over a thin flat strip at zero angle of attack or a tube in crossflow
• Water temperature (T?) = 40°C
• Tube diameter = D
• Strip width = ?D/2
• Tube and strip length = L
• Reynolds number: 50 < Re < 1000
FIND
• The ratio of the heat transfer from the strip and that from the cylinder. (qs/qt)
ASSUMPTIONS
• Steady state for both cases
• The tube and strip temperatures (Ts) are 90°C SKETCH
PROPERTIES AND CONSTANTS
for water at 40°C: Prandtl number (Pr) = 4.3 At the surface temperature of 90°C: Prs = 1.94
