Answer Posted / allu phanindra
p=t*w
where p is power
t is torque
w is angular velocity
we know that angular velocity is does not depends up on the diameter of the shaft therefore power is directly proportional
to only torque
t=f*r
where f is force and r is radius
from the above relation we can say that power is directly proportional to diameter
power transmitted by shaft B is twice as shaft A

Hai, iam renjith. my qtn about the calorex heat and cool pump. What is the reason of the above machine is trip on high pressure. r134a gas using in this system. 8 months old. model is calorex propac 90(3 phase). This system has 2 compressor. Both are starting on 13amps after that rise up to around 21 within 1 minute. After will be trip on high pressure. Showing 68 psi in suction side on standby mode. Can i have a solution without delay?
