Pipe Schedule and Size Pipe Outer Diamater (OD) 0.84inches Pipe Inner Diamater (ID) 0.622inches Wall thickness 0.109inches Velocity and Friction Loss Velocity and Friction Loss are derived from the the nominal pipe size chosen fromPipe Schedule and Sizeand pump flow rate....
Overall head loss in a pipe is affected by a number of factors which include the viscosity of the fluid, the size of the internal pipe diameter, the internal roughness of the inner surface of the pipe, the change in elevation between the ends of the pipe and the length of the pipe ...
Use a flow vs. pipe-loss data chart to determine the pressure-drop flow correlation. Reading this type of table, the flow rate corresponding to 3.8 psi loss to 100 feet of 2-inch Schedule 40 PVC plastic pipe is 75 gpm. 4. Determine the Pressure Loss ...
Since you can also use schedule 40 pipe for a return line, you can check the schedule 40 chart again to determine the proper pipe size. By looking in the 15 feet per second column of Table 2, you find that a 1-inch return line can deliver up to 40.6 GPM without exceeding 15 feet ...

The Moody friction factor can be obtained by plotting the Darcy friction factor as a function of Reynolds number and relative roughness. The Moody friction factor is four times larger than the Fanning friction factor; it is important to note, in a “friction factor” chart or equation, which ...
The owner noticed extremely high gas bills as compared to the first floor. A system survey found that the pump size for the second floor was incorrect. A recalculation was made and a new pump was installed. The gas bill for the second-floor unit actually began to be less than the first...
