AI Thread Summary
To calculate fluid velocities in a 150mm and 300mm pipe system delivering water at 7500 liters per minute and 820 kPa, the continuity equation m = p1A1v1 = p2A2v2 is appropriate. The discussion confirms that continuity is sufficient for determining flow rates, given the areas of the pipes. The focus is on applying the equation correctly to find velocities in both sections of the pipe. The gradual expansion from the smaller to the larger diameter is also noted as a relevant factor in the calculations. Accurate application of these principles will yield the desired fluid velocities.

Homework Statement



A pipe of 150mm bore is delivering water at a rate of 7500 liter/min at a pressure of 820 kPa. It connects via a horizontal, gradually expanding pipe, to a main of 300mm diameter. calculate the fluid velocities both in the main body of the pipe and at the outlet.

Homework Equations



m= p1A1v1 = p2A2V2


The Attempt at a Solution



Is the equation above correct to use for this problem. Thanks in advance.

Yup, if all you're concerned about is flow rate, then continuity is all you need assuming you have areas...which you do!

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
