Need a formula to figure pulley sizes ?

D2 = D1 x N1                   
   _______                                                                         

       N2                                    

                                              
D1= Diameter of pulley on engine 
D2= Diameter of pulley on generator
N1= RPM of engine
N2= RPM of generator   

 

1 HP = 33,000 foot-pounds per minute (550 foot-pounds per second).
Torque (in foot-pounds) = BHP x 5,250 / RPM
BHP = Torque(in foot-pounds) x RPM / 5,250
BHP = torque (inch-pounds) x RPM / 63,025
1 Btu = 778 foot-pounds
1 HP = 2,544 Btus
1 KW = 1.34 h.p.
1 KW = 3,413 Btus
100 cubic inches = 1.64 liters
