To produce electricity under a 30 meter high dam, one unit of electricity requires 6.5 cubic meters of water. According to the relevant public information request: the atmospheric pressure is 0.8 MPa, the water height is 80 meters, 6.5 cubic meters of water can generate one kilowatt hour of electricity. When 40 cubic meters of water are used, 6.15 kilowatt hours of electricity (take). 6 degrees), 2 kW can be generated for 3 hours, provided the air pressure is kept constant.
