Acylinder is fitted with a piston, beneath which is a spring, as in the drawing. the cylinder is open at the top. friction is absent. the spring constant of the spring is 3900 n/m. the piston has a negligible mass and a radius of 0.020 m.
a) when air beneath the piston is completely pumped out, how much does the atmospheric pressure cause the spring to compress?
b) how much work does the atmospheric pressure do in compressing the spring?

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
