Discharge side........
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.

When the ship is at the port, the water is shallow therefore we use high seawater suction. If the low seawater suction was used instead, impurities such as sand would be sucked into the system..
suction head is calculated wiht the formula head = 2.31 x psi so if your suction is 30psi then your head is around 60ft. of head. If your suction head is to high then there is not enough water to pump the needed psi for the task
Suction is caused by an are of negative pressure.
when pressure on the suction side of the pump drop below the vapour pressure of the liquid, vapour forms. It's caused because of insufficient suction head, high suction lift, excessive friction head, or high liquid temperature.
The suction line will be the larger line going into the compressor.
To compensate high suction volume during startup of he pump. the reducer area below the pipeline at the suction stores excess volume of fluid.
discharge pressure is high, suction pressure is high superheat is low and subcooling is high.
Low side.
When you stick a suction cup on a window you force the air out of the suction cup and you create a high pressure vaccume keeping the suction cup on the window.
