    How Long Does It Take for Connected Water Tanks to Equalize Pressure?

    Thank you for the reply. The detail of the problem is that two tanks have pressure 87psi and 40 psi respectively. The 40psi tank connects to the water main. The 87psi tank has a expansion tank connected. When they are connected together, is it possible to know how pressure in the 87psi tank...

    How Long Does It Take for Connected Water Tanks to Equalize Pressure?

    Hey, I have a problem in which there are two water tanks with different pressure. If they are connected together, how to calculate the time it takes to arrive to the steady state(same pressure)? Thank you.

    Help me with the leakage rate of a crack in a pressure pipe.

    Thank you for your answer. The glycol/water mixture is circulated by the pump from the collector to the storage tank where the heat transfer occurs. The glycol/water mixture carries the heat from the solar collector to the cold water in the tank. The high pressure is not due to water hammer but...

    Help me with the leakage rate of a crack in a pressure pipe.

    Sorry for lack of information. The leak occurs in the heating coil in a water storage tank of a solar hot water system. The glycol/water mixture in the collector loop expands due to the stop of the pump. Under the high pressure, we assume there is a crack in the heating coil. So I am thinking...

    Help me with the leakage rate of a crack in a pressure pipe.

    stewartcs, thank you for your reply! I have another question here. If I use Bernoulli's equation, the pressure at upstream must be constant. What if the pressure is decreasing with time since the water is flowing out? Thank you for any approaches.

    Help me with the leakage rate of a crack in a pressure pipe.

    I am thinking about the following situation. In a stagnation water loop, the pressure is building up. A crack occurs due to the expansion of the water. What will be the solution approach to determine the flow rate of the leakage? Please give some hints or references. Thank you.
