cylinder weight: 17000 lb weight , Diameter = 36"= 3 ft, length = 5 ft. , 3000 rpm , time=90 sec.

Aceee = Change in angular velocity / time

Angular velocity = 2xPi (3.14) 3000/60 = 314rad / sec

acee = ( 314-0) / 90

= 3.48 Rad / sec2.

Torque = force x radius

= 17000 x 1.5 = 25500 lb-ft

Power = torque x omega

= 25500 x 314

= 8007000 lb-ft / sec

1 hp = 550 lb-ft / sec

Hp = 8007000 / 550 = 14558 HP

Actuaalyy i need to rotate that thing in 90 second so where can i find that? 14558 hp is too much i think . i am doing something wrong somewhere please help me on that
