Enter the length of your pipe in feet from the collection point to the generator.
Below are the inner diameters of different types of pipe.
Pipe "Size"- 1 1.5 2Actual inner diameter for PVC SH 40- 1.05 1.61 2.07Actual inner diameter for PVC SH 80- 0.96 1.50 1.94
Static PSI 21.65PSI loss due to pipe friction- 0.58
PSI Loss Percentage- 2.7% This number should be below 8%! The lower the better!Flow Velocity in Feet Per Second- 2.55 This number should be below 5, and preferably 3 or less.

Welcome to the hydroelectric calculator made to get the optimal energy from your water source. RockyHydro matches your water sources' flow and head specifics to the perfect turgo turbine and generator combo to give
you the most efficient micro-hydroelectric system on the market.
Enter the gallons per minute available from your stream. It is best to enter 80% of the flow at your water sources' lowest yearly flow to be safe.
Enter the feet of elevation that the water drops from the collection point to your generator.
PENSTOCK LENGTH=
Note: Schedule 80 pipe is thicker and more suitable for greater pressures. The PSI ratings may vary so check with your pipe supplier before making your final decision. You may be able to use SH40 for the top of your penstock and SH80 for the lower part which is at greater pressure.
To choose an adequate pipe for your system, enter an inner diameter here. Find a diameter that keeps the head loss below 8%. You also want to keep the flow rate below 5 feet per second, especially with pressures higher than 80 PSI, or in pipe
larger than 2". This calculator is based on the Hazen-Williams formula, which is the industry standard, yet it is empirical and not 100% accurate. It is based on smooth PVC pipe sides, in a straight pipe with a minimal amount of joints and bends, and a
water temperature between 60-70 degrees F.
Inner Diameter=
Enter a friction loss multiplier here to account for the number and type of joints in your system.
TIP! If you are planning on doing a finished LOW-HEAD system leave this as a 0 since you won't have a penstock at
all!
If pipe is relatively straight, with minimal straight joints and only one or two 45 degree joints…
Enter a 1.0 above
If pipe has minimal straight joints, only one or two 45 degree joints, and one or two 90 degree joints…
Enter a 1.2 above
If pipe has multiple, energy sapping 90 degree joints…
Total estimated percentage loss- 0.0%

Based on your GPM and PSI, you can have either:
1 nozzle that has a bore in MM of- 21.55
2 nozzles with bores in MM of- 15.24

Orange 16 149.1 1063
Enter a 1.5 above
If this number is greater than 10% we suggest you select a larger pipe diameter for your system, reduce the penstock length, plan on less GPM
in your system, or reduce the number of friction-causing joints!
This is not a guarantee! However, we have erred on the conservative side and believe you will be pleasantly surprised by your system's true efficiency. We've heard of systems
receiving an additional 10% than what is calculated here.
These numbers are based on "water to wire" efficiency and do not account for losses in other parts of your system. (chargers, inverters, ect;)

$ saved 10 years with 5% increase in price per year-
Now that you have a reasonable estimate of your net PSI, GPM, and the watts your stream should be able to produce, you can begin to build your system.
Your turbine works most efficiently at 48% of the velocity of the water jet. Based on your NET psi, the following table shows your target RPMs with different turbine
wheel sizes:
Note - Stainless Steel metal turgos are recommended for heads above 350 feet, and are required for heads above 600 feet. Other than that, the more econnomical injection-molded hard plastic turgos work just
fine.

Note - Stainless Steel metal turgos are recommended for heads above 350 feet, and are required for heads above 600 feet. Other than that, the more econnomical injection-molded hard plastic turgos work just

As you can see, there are different RPM options based on the turbine size. Next, RockyHydro matches a motor that will produce the power your have available at these RPMs to make an incredibly efficent hydro system. We have over 400 systems available to ensure one will fit
your site. Please head back to our website www.rockyhydro.com to purchase your system online, or email us at [email protected] if you have any questions or if you aren't finding exactly what you are looking for.
