Consider an internal flow through a circular tube. Assuming hydrodynamically fully developed condition, the velocity profile is given as ??(??) = 2????????(1 ? ??^2/??^2 ). For constant surface heat flux case,

a) Calculate NuD for thermally fully developed condition.

b) Also, plot variations of tube surface temperature and mean fluid temperature along flow direction (x) including entry and fully developed region.

c) Can you plot variation of convective heat transfer coefficient (h) along flow direction (x) including entry and fully developed region.

(a) Fluid at a mass flow rate of 0.352 kg/s flows through a tube with a diameter of 15 mm and a length of 25 m. The inner surface of the tube is heated with a uniform heat flux of 1000 W/m2. Measurements shown that the inlet temperature of the fluid is 30 ˚C. Assume the outer surface of the tube is perfectly insulated. Consider the thermophysical properties of the fluid are as follows: density ρ = 1000 kg/m3, specific...

Consider a vertical parallel-plate channel of indefinite length, with walls at different temperatures. The channel width is 2L and the wall temperatures are T1 and T2. It is assumed that T2 > T1. In this system, the heat fluxes in and out of the fluid will come into balance, yielding a thermally fully developed region with no streamwise temperature variations. With the temperature (and buoyancy) force independent of x, it is feasible to have fully developed flow. (a) Sketch the...

Combustion gases passing through a 2.3-cm-internal diameter circular tube are used to vaporize waste water at atmospheric pressure. Hot gases enter the tube at 115 kPa and 250°C at a mean velocity of 5 m/s, and leave at 150°C. If the average heat transfer coefficient is 120 W/m2 °C and the inner surface temperature of the tube is 112°C, determine the tube length. Answer in cm with two(2) decimal places.
