A bicycle can be used to generate electric power by attaching a loop to the axle and letting it rotate in a magnetic field. Suppose such a device is attached to a bicycle with a 65 cm diameter wheel.
(a) What is the velocity (in m/s) of the bicycle if the generator's angular velocity is 63 rad/s?
(b) What is the maximum emf of the generator when the bicycle moves at 3.5 m/s, noting that it was 17 V under the original conditions?

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.
