Does anybody know where I can purchase a hydraulic slide rule which would allow easy checking of friction losses, and velocities thro' various pipe types and diameters? We have one only in our office, but it dates back some time and we cannot find out where it came from! They are very handy when...
Whenever I have reducing fittings (tees, elbows) I always show the change in direction going through the smaller diameter, so you seem to be on the right track...
Incidentally, do you ever make an allowance for grooved couplings in the pipeline...if so, what?
Hi, what formula can I use to calculate the required minimum diameter of a pipe where the flow rate is known, and where the velocity is specified as being a maximum of 1.5metres per second?? Fluid is clean fresh water.
