Hi All-

New member here. As the title states I am trying to solve the flow volume of water from a pressurized storage tank through a heat exchanger and then discharging out the end of a pipe. I have been working on this for several days now without any luck, seems like now I am just throwing equations at it and hope something sticks. So I could use a nudge in the right direction.

The storage tank is a bladder tank in that air pressure is one side of the bladder and water on the other.

From the bottom of this tank the water flows through a heat exchanger. All I have on the heat exchanger to work with is (3) data points relating change in pressure with flow rate. I used curve fitting software to come up with a quadratic equation to describe this.

The water exits the heat exchanger and just empties into the open.

I have been using Bernoulli’s Equation to try and solve this. All my units should be a match. Volume in cubic feet, Area in square feet, pressure in pounds per square foot, density in pounds, time in seconds. Attached is a spreadsheet of my latest attempt. I apologize for how messy it is.

Thanks for you help!
