Does Pipe Size Reduction Affect Flow Rate and Pressure Drop Significantly?
0http://math.stackexchange.com/questions/946493/solve-for-pressure-drop-across-and-orifice# I'm running 1/2" pipe but the only way to connect a 9/16" flow switch is with a 1/4" adapter. I'd have to go from 1/2" down to 1/4" to the 9/16" flow switch down to 1/4" back to 1/2". I was wondering if...- JJ1989

Calculate Motor Torque for Running 8 Pulleys off One Motor
Bump, any input on if I'm using the correct calculations to size the motor or if there is a better equation? The less power use the better but I don't want to burn it out by under powering it either.- JJ1989

Calculate Motor Torque for Running 8 Pulleys off One Motor
At different points on the ceiling will be 8 different pulleys and one motor/drive pulley. Each pulley will have a bracket welded to it in order to expand the diameter. From this bracket will be a few wires holding up some sort of halloween type object all pretty close to 20lb. At most they...- JJ1989

Calculate Motor Torque for Running 8 Pulleys off One Motor
My apologies billy joule, I plan to connect the 8 pulleys using a belt like used on the belt driven ceiling fans. Each pulley will have a load of 20lb attached to it. The pulleys will not actually be 19" but the load will be 19" off center of rotation(weld bracket to pulley), the 8 pulleys...- JJ1989

Calculate Motor Torque for Running 8 Pulleys off One Motor
I would like to run 8 pulleys off of one motor. Each "pulley" would be 19" in diameter with 20lb of weight at 30RPM. I would like to know how to calculate the inch-lb that would be required of the motor. I read this on masterdrives.com Torque(inch-lb) = (.03908 x N x W x R^2)/t Where N...- JJ1989
