4.9.10. Mock up your manifold off-site first
You will save a lot of time if you mock up your manifold and exhaust water collection off site
where it is easier to work. This picture shows 2 x PLT100C turbines trial fitted off site prior to
carrying all the parts 800m into dense forest. Note the mac unions so that the turbines can
be easily removed.
4.9.11. Other manifold options
There are many possible manifold solutions; there are some pictures below to give you ideas
for your situation.
4.9.12. Measuring pressure in your pipe and manifold
Pressure losses in your Penstock and manifold are typically in the range 5-33%, with a 10%
loss typical (used as the default in the online calculator). It is very helpful if you can measure
both the static and dynamic pressure at the end on the Penstock and just prior to the turbine
jets. From these readings you are then able to determine the losses in the Penstock and the
losses in the manifold. All PowerSpout turbines (other than discounted twin packs) include a
pressure gauge.
