Acartridge electrical heater is shaped as a cylinder of length l = 200 mm and outer diameter d = 20 mm. under normal operating conditions the heater dissipates 2 kw while submerged in a water flow that is at 20°c and provides a convection heat transfer coefficient of h = 5000 w/m2 · k. neglecting heat transfer from the ends of the heater, determine its surface temperature ts. if the water flow is inadvertently terminated while the heater continues to operate, the
