In a 770 kw hydroelectric plant, 300 m^3 of water passes through the turbine each minute. assuming complete conversion of the water's initial gravitational potential energy to electrical energy, what distance does the water fall? assume two significant figures.

16 m

Explanation:

given,

power of hydraulic plant = 770 kW

volume of water pass through the turbine = 300 m³

density of water = 1000 kg/m³

m  =ρ × V

mass of water pass each minute  = 300 × 1000 = 3 × 10⁵

assume height of the fall be h

potential head of the water = mgh

h = 15.69 m ≈ 16 m

the distance of the water fall is equal to 16 m.

the results is a decrease in air temperature with an increase of altitude.

explanation:

connectedness in handwriting analysis is a useful tool in establishing the writer’s method of thinking and its perception in where he/she fits in to the environment around him in the social sense. in addition, the more connected the writing of an individual, the more he/she is flexible and single minded.
