Finding Turbine Angular Velocity given Net Head, GPM, and power from Alternator.

Click For Summary
To find the angular velocity of a water turbine given the net head, flow rate, and power output from the alternator, additional information is required, specifically the average radius of the turbine blades. The alternator generates 35 Watts at 50 feet of head and 10 gallons per minute, with an efficiency of 50%. This implies that the actual power input to the turbine is 70 Watts. Without the radius, calculating angular velocity directly from the provided data is not feasible. Therefore, obtaining the average radius of the turbine is essential for determining the angular velocity.

An alternator attached to a water turbine generates 35 Watts given 50 feet of head and 10 gallons per minute. Assuming that the efficiency of the alternator is 50%, is it possible for me to find the angular velocity from this information?

If so, how would I do it?

humm...im not sure if I am right but assuming your trying to find the angular velocity of the turbine blades? then i think you need more information such as average radius of the turbine where the blades are. But I am not even sure if your taking about that...
 

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
