  1. A car possessing the speed of 1000 revolutions per minute has a torque of 50 pound foot. Calculate its rotating Horse power.


    Step 1 :  

    Given: Torque $\tau$ = 50 lps, speed N = 1000 revolutions per minute



    Step 2 :  

    The Power is given by
    Power = $\frac{\tau \times N}{5252}$


    = $\frac{50 \times 1000}{5252}$
    = $\frac{50000}{5252}$
    = 9.52 hp.



    Answer  :  

    Power = 9.52 hp.



  2. A bike has a torque of 100 lbs and power of 100 hp. Calculate its speed.


    Step 1 :  

    Given: Torque $\tau$ = 50 lbs, power = 100 hp



    Step 2 :  

    Power = $\frac{\tau \times N}{5252}$

    N = $\frac{100 \times 5252}{100}$

       = 5252 revolutions per minute



    Answer  :  

    Speed N = 5252 revoltuions per min
