Water Flow Rate from a Tank: Geometry or Level?

AI Thread Summary
The water flow rate from a tank primarily depends on the pressure head, size, and shape of the opening rather than the tank's geometry. The formula V=Cd(2gh)^(1/2) indicates that flow rate is influenced by these factors. However, the time it takes to empty the tank can be affected by the tank's size and geometry. Therefore, while geometry does not directly impact flow rate, it plays a role in the overall emptying time. Understanding these principles is essential for accurate calculations in fluid dynamics.

Hello guys,

I want to know whether the water flow rate from a tank depends on the geometrical shape of the tank (for instance sperical, rectangular, cylindrical) etc or it just depends on the water level in the tank. Thanx.

Well if the flow is through a (relatively) small opening, the instantaneous flow rate is dependent on the pressure head, size of opening, and shape of opening.
V=Cd (2gh)^1/2
Q=VA
So tank geometry doesn't come into play. Time to empty would be affected by tank size & geometry.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
