A12 v car battery supplies a dc shunt motor. the motor shunt coil resistance is 15 ? and the armature resistance is 0.03 ? . in open circuit conditions, the motor speed is 700 rpm, and its input current is 5 a. calculate the motor speed at a load of 0.5 hp. answer should be around 649 rpm

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
