I done this calculation But something wrong.
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
