Let's assume one of the inlet ports is at atmospheric pressure, Absolute pressure = atmospheric pressure + differential pressure = 14.7psi + 43psi = 57.7 psi
Let me differentiate first between design pressure and mechanical design pressure. Design (or discharge) pressure is the pressure at the outlet of the pump, the pressure you've designed the pump to deliver. The mechanical design pressure is a value that the pump casing and downstream piping have to be able to withstand as a minimum*. I presume you mean design pressure as discharge pressure. In this case, differential pressure is the difference between the discharge pressure and the suction pressure (the pressure at the inlet of the pump**). * this is calculated taking into account that a pump would be working against a 'blocked discharge' or a closed valve in the outlet piping ** imagine a reservoir filled with liquid

This is the pressure supplied from the gas meter to a appliance this should be 20mb at the inlet of the gas valve before the appliance is working ie taking gas from the main pipe.

For most AC systems, the outlet of the expansion valve or orifice tube is where the low pressure side begins, which includes the evaporator and the inlet of the compressor. In between the metering device outlet and the compressor inlet, you'll have the evaporator. In a Fixed Orifice Tube system, the accumulator will also be on the low pressure side.
usually hydrogen or helium gas were choose as inlet gas/ carrier from evaporator to absorber coil. Inlet gas contribution toward total pressure in the system where according to formula to determine partial pressure in the system PTOTAL SYSTEM = P HYDROGEN (inlet gas ) + P AMMONIA (REFRIGERANT )
I am not exactly sure of what you are asking but there is not an evaporator valve. There is an evaporator core that resembles a radiator and there are not any parts that can stick. The only problem they have is leaking. There is an orfice that goes in the inlet to the evaporator and it has no moving parts.It can get stopped up and cause the high side pressure to get higher than normal.
The orfice tube is located in the evaporator inlet tube. There is also an expansion valve in the rear evaporator case.

Between the receiver-drier outlet and the evaporator inlet.
It starts at the outlet valve of the metering device and ends at the inlet valve of the compressor. The evaporator is on the low pressure side of the system, as is the accumulator, if your vehicle has a Fixed Orifice Tube system.
It is located in the inlet side of the evaporator.
It is located in the inlet tube of the evaporator between the outlet of the condenser and the inlet of the evaporator. This point can be found in a properly functioning system by locating the area between the outlet of the condenser and the inlet of the evaporator that suddenly makes the change from hot to cold. You can see small dimples placed in the line that keep the orifice tube from moving inside the tube. It is located just a few inches outside of the condenser in the tube.
Inlet pressure/discharge pressure
Some are in the inlet to the evaporator and some could be in the condenser line.
In the inlet line on the evaporator core. It is the smaller one.
