There isn't, you have to measure it directly or via a flow measuring device, or refer to the manufacturer's tables and calculate it from those.

Static discharge head refers to the pressure at the pump discharge outlet, which is created by the pump's rotation and used to overcome the system's resistance to flow. It is a critical parameter in pump performance calculations and determines the pump's ability to push water through the system. Static discharge head is influenced by factors such as pump design, speed, and the system's piping configuration.

Bleed the air out while running your pump. Either through a specific bleed valve or by loosing the discharge pipe at the pump until only fluid runs out of it.
centrifugal pump should be fill with liquid to built discharge pressur.chemist.yasser.Naguib
if the discharge of centrifugal pump is closed the pressure is built up in it and after some time it will burst up
The power required by a reciprocating pump is directly proportional to the discharge it produces. When the discharge increases, the power needed to maintain that flow rate also increases. This relationship is governed by the pump efficiency and the pressure head against which the pump is operating.

The pump discharge reducer doesn't matter if it's concentric or eccentric. It's the pump SUCTION that needs to be an eccentric reducer that is always flat on top (F.O.T.) The eccentric reducer on the pump suction reduces pump cavatation (pump catching air).

A blockage in the downstream side of the pump could make this pump work harder raising the amps as the pump now has to do more work to get through the line. An upstream blockage would make the pump spin more freely lowering the amps on the pump as it will not be doing any work.
The recommended sump pump discharge pipe size for optimal performance and efficiency is typically 1.5 inches in diameter.
