If a pump moves at 90 gallons per minute , what is the volumetric flow rate in units of cubic inches per second?

Assuming US gallons, 346.5 cubic inches per second.

The number will be slightly different for Canadian or Imperial gallons.

How many gallons per minute can flow thru a 1/4 inch valve with 150 psi

well=== pure water flows at 5.1 gpm thru 1/4 pipe , now valves have a slight orifice to slow the flow down some as a 1/4 valve most likely has a 1/16 orifice value , but that's just an educated guess as I don't know what valve u have , also im assuming your using pure water with a specific gravity of 1.0000 (yes it effects the rate) say hydraulic oil has a value of .0898 this will also slow the flow thru the valve

My D55141 heavy duty 2gal (7.6L) 150 psi max builds pressure up to around 150 releases pop off valve then keeps running, what causes this problem?

The pressure switch is either out of adjustment or has failed. The compressor should shut off at a much lower pressure than the safety valve (~100 psi)

Regulator will not exceed 90 psi.

It is possible to replace the regulator with a higher capacity regulator. Almost all air tools warn against using more than 90 PSI, and I think that your regulator is limited to 90 PSI for safety reasons... (but why on a compressor capable of 150 PSI I don't know). If you need more pressure, buy a replacement regulator (doesn't have to be Sears) and use a 1/4 inch nipple or a short length of air hose to connect it to your compressor.

Can you use a draper submersible pump for a garden irrigation system to use with several sprinklers, does it provide enough water pressure on the outlet?

Here's how to tell.
Connect a tee to the outlet of the pump.
Install a pressure gauge in the tee.
Install a valve after the gauge.
Open the valve and start the pump.
Once water flows, close the valve slowly until you get 50 psi on the gauge.
Have a 5 gallon bucket nearby and measure how long it takes to fill the bucket at 50 psi.
If it fills the bucket in 30 seconds, you can attach heads to the pump that combined consume 10 gallons per minute.
Let me know how you do.

PR650NBRT Hot Water Heater (mfd. by State Select?) 50 gallon , natural gas, expansion tank is installed on outlet pipe Serial #AO1124263, 150 PSI, In the upstairs furnace room (where HWH is) the collection...

The one drip per second is about correct, it's the water vapour coming from th combustion of the gas that condenses But is shouldn't puddle, it should completely drain immediately so something is wrong there - most likely it was badly installed.
The rest of the puddles are also created by a bad install: an bad seal at the pipes connections.
That nut on top is the safety valve, nothing should go out of there. If there is water seeping from it then the expansion tank is completely full and that is dangerous, it can fail.
I must say that the entire system has been installed by monkeys. It should be dismantled and all the connections redone by someone who really knows how to do it properly.
