What power is transmitted by belt and pulley arrangement, if tension on tight side of belt is 60 kg and tension on slack side is 25kg. The diameter and speed of driving pulley is 0.95 m and 250 rpm respectively.

a) 5.239 KW
b) 9.624 KW
c) 2.264 KW
d) 4.269 KW

Answer: d
Explanation: peripheral velocity = \(\frac{πDN}{60}=\frac{π*0.95*250}{60}\) = 12.4354 m/s
P = (T1-T2) * V
P = (60-25) * 9.81 * 12.4354 = 4.269 KW
