You drive a car on a winter day with the atmospheric air at -15°c, and you keep the outside front windscreen surface temperature at +2°c by blowing hot air on the inside surface. if the windscreen is 0.5m² and the outside convection coefficient is 250w/m²k, find the rate of energy loss through the front windscreen. for that heat transfer rate and a 5mm thick glass with k=1.25w/mk, what is the inside windscreen surface temperature?
