Answer :
When check valves are connected in parallel, the system behaves such that each valve operates independently. For the flow to occur, at least one of the valves must be open. However, in a parallel arrangement, the pump must provide enough pressure to meet the requirement of the valve with the highest pressure rating since it will be the limiting factor. This means that the minimum pressure required at the pump is the highest pressure rating among the valves.
Here are the pressure ratings for the check valves in this setup:
- Check Valve 1: 50 psi
- Check Valve 2: 100 psi
- Check Valve 3: 200 psi
To determine the minimum pressure required at the pump for flow to occur, consider the valve with the highest pressure requirement. In this case, that is the third valve with a pressure rating of 200 psi.
Therefore, the minimum pressure required at the pump to ensure that flow occurs through the parallel-connected check valves is:
200 psi
