The heat transfer rate due to free convection from a vertical surface, 1 m high and 0.6 m wide, to quiescent air that is 30 K colder than the surface is known. What is the ratio of the heat transfer rate (i. e. q1/q2) for that situation to the rate corresponding to a vertical surface, 0.6 m high and 1 m wide, when the quiescent air is 30 K warmer than the surface?

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
