how do I calculate a pumps psi output?

I want to attach another device to the pump and it requires a certain psi to function properly.

Thanks for the clarification.

The chart gives you the pressure just at the discharge of the pump. If after the pump, your pipe goes upward, The pressure on the top is less than that. Add friction too, though friction can be reduced to a small value. If the pipe goes horizontally, The psi of the end of the pipe is something between 5.0 and 6.0 psi. If the pipe goes upward, reduce 1.5 psi per meter from the value of horizontal case.

Thank you for resolving this problem. As you said the chart gives you the answer automatically if you know how to interpret it correctly. That's all I guess and have a good day.
