4.7. The Penstock

The online advanced calculator at www.powerspout.com/calculators/ will have advised the

appropriate internal diameter (ID) of pipe for the "penstock" or pipeline, based on the site

data you entered. You should position the PowerSpout to obtain the greatest fall possible in

the shortest distance.

For initial feasibility you can use a map and/or gps to survey penstock options. When you

have chosen the locations for the intake and the turbine, measure the pipe length using a

long tape or wheel, be accurate, as this information will be required to buy the pipe and it’s

important to get it right.

Try to lay the pipe to avoid high spots in the line that might trap air bubbles. Use a level to

check that it is always graded downward. If a high spot is unavoidable you will need to place

a bleed valve at the highest point in the pipeline to purge air. Air locks in the line will

significantly affect the power output of the turbine. The longer the penstock the more of a

problem this tends to be. Penstocks over 1 km long can be problematic if there are many

high spots trapping air. Automatic bleed valves may be useful in such cases.
