How can I test the load output of my hydro turbine without breaking the bank?

AI Thread Summary
To test the load output of a hydro turbine on a budget, consider using an old generator with a defective engine, which can be found at a lower cost. A generator rated for the desired power output, such as 4 to 7 kW, can provide accurate load data without significant expense. Alternatively, using a heavy truck 24V alternator to measure amp output is another option, though it may require ensuring the alternator can handle the necessary load, around 200 amps. These methods offer practical solutions for obtaining load output data without breaking the bank. Exploring second-hand equipment can significantly reduce costs while providing the needed functionality.

Hi Everyone, I am building a hydro turbine, I am expecting it to produce circa 4 kw possibly as high as 7 kw depending on flow. I am on a very limited budget. Please could you suggest possible means of getting load output data? I have considered attaching a heavy truck 24 v alternator and doing a simple calculation from amp output but I'm not sure I can get a big enough alternator, around 200 amp?
Thanks
Nick

Find yourself an old generator of the proper power output, ideally with a defective engine to keep the cost down. For example, something similar to this http://www.ebay.com/itm/Robin-Rgd-5000-Watt-Diesel-Generator-For-Parts-/111523201105?pt=BI_Generators&hash=item19f74d0051.

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
