The inner tube surface may be assumed to be isothermal at 100°C, and the outer tube is well insulated. Assuming fully developed Poiseulle flow for oil, determine the rate of heat transfer to the oil from the tube surface and find the tube length required to heat the oil to the indicated temperature using the empirical relations associated with convection heat transfer.
