Answer Posted / ronak pujara
according to me, increasing the stages of turbine, keeping the pressure drop across the whole turbine same, pressure drop across each stage will reduce which will reduce the stage efficiency or blade efficiency of the turbine...hence chances of corrosion of the blades and pitting will increase...the size of the turbine also increases in turn...hence no of stages are decided on the basis of stage efficiency and pressure drop across each stage required...

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?
