An electric resistance heater is embedded in a long cylinder of diameter 30 mm. When water with a temperature of 25 oC flows crosswise over the cylinder, the power per unit length required to maintain the surface at a uniform temperature of 90 oC is 28 kW/m. (a) Determine the heat flux through the cylinder surface. (b) Determine the convection heat transfer coefficient.
