# Orlík hydroelectric plant

The Orlík hydroelectric power plant, built in 1954-1961, consists of four Kaplan turbines. For each of them, the water with a flow rate of Q = 150 m

a) What is the total installed power of the power plant at efficiency n = 87%?

b) For the fast charging of electric vehicles overnight, power consumption up to P0 = 11kW is required. How many would electric cars cover power plant power?

c) How many days of full power operation corresponds to the delivered energy E = 398GWh

^{3}/s is supplied with a flow rate of h = 70.5 m at full power.a) What is the total installed power of the power plant at efficiency n = 87%?

b) For the fast charging of electric vehicles overnight, power consumption up to P0 = 11kW is required. How many would electric cars cover power plant power?

c) How many days of full power operation corresponds to the delivered energy E = 398GWh
