no I am not aware of that, how is the theory relates to what i need?

what if a pretty tight 90 degree bend is required? due to space constraint? will using larger diameter 90 degree bend helps to smooth out flow? i.e. 1.5" straight pipe > 2" diameter 90 degree elbow > 1.75" straight pipe > 1.6" straight pipe > 1.5" pipe instead of 1.5" > 1.5" 90 degree elbow >...

i have read somewhere on the net that a 2.5" diameter of 90 degree elbow have equivalent flow of 1.6" straight pipe of same length as the bend. any way to figure out how the statement above is derived?

since the gases are cooling, it gets slower as they travel thus the reason I am considering a converging pipe, true? the header has same diameter throughout, the diverging pipe i mentioned was after the merge of all primary pipes. something like this: what is ur opinion? what if i...

i wish to design an exhaust system of my project car for minimum flow losses lets not focus on the exact figures just yet, just wish to confirm whether my design theory would work the setup would be something like this exhaust header > 7" length downpipe > 90 degree elbow > 20" straight pipe...

can someone explain to me why it seems that the smaller the diameter of pipe bend (i.e. 90 degree elbow = 30D) the shorter its equivalent length becomes? for 1.5" diameter = 45" equivalent length while 2" diameter = 60" length. does this mean 1.5" diameter 90 degree elbow has less friction than...
