A tank car containing 4500 gal of 32% HCl is pressurized by air to 15 psig and sent through 100 ft of 2 inch schedule 80 PVC pipe. The receiving tank at the other end is at atmospheric pressure. Estimate the flow rate through the pipe and the time to empty the car. Assume the pressure in the tank car is constant.
The flow rate required to empty HCl from a tank car is calculated.
