Water at a mass flow rate of 0.3 kg/s is cooled from 70oC to 30oC by passing it through a thin walled tube of diameter D=.05 m. Also air coolant passes over the outside of the tube in cross flow at T[infinity]=15oC with a velocity of 18 m/s. Assume negligible conduction in the wall and steady state conditions. Assume a film temperature for air of 300K

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
