Determination of the overflow port size for atmospheric pressure rectangular tanks
Thread Content
Currently, the medium inside the atmospheric-pressure rectangular tank is an alkaline solution. The tank is equipped with an overflow port to maintain atmospheric pressure. Since an electric heating system is installed in the tank, the temperature of the alkaline solution remains around 80°C. How should the size of the overflow port be determined in order to maintain atmospheric pressure?
Should the overflow port still be determined according to the standards for atmospheric-pressure tanks?
I don’t know what the size of the tank is, or what its effective volume is For this, a pipe with a diameter of 80 or 100 will suffice; no calculations are needed
1. What are the inlet and outlet pipe diameters and the maximum flow rate? This information can be used to calculate the fluctuation speed of the tank level； 2. What is the maximum clear height at the top, so that the expansion and contraction of the gas phase due to temperature changes can be calculated? ；
Is there a formula for calculation? Or a reference standard?
It depends on your feed pressure and flow rate, as well as the design pressure of your tank; it’s important to ensure that discharge occurs in time to prevent the tank from overpressuring
