Engine oil at a hundred degrees Fahrenheit passes through 1/8 inch diameter tube at a volume flow rate of 50ft³/m . If the surface temperature is 150 degrees F, what is the heat transfer rate Q.

Q = ?????? Btu/h. Assume a smooth surface and the tube length is 5 meters.

From the book use p (density) = 54.24 lbm/ft^3,_,

Specific heat = 0.4809 Btu/(lbm*R) R=Rankin,

Thermal conductivity = k= 0.08207 Btu/(h*ft*R)

u = 7.617 * 10 ^-2 lbm/ft*s, u = fluid viscosity

Pr = 1607, Pr = Prandtl number
