Acoil of 300 turns, wound on a core of non-magnetic material, has an inductance of 10 mh. calculate:

a. the flux produced by a current of 5 a;

b. the average value of the e. m.f. induced when a current of
5 a is reversed in 8 ms (milliseconds).

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
