Answer:
The water must flow with the velocity of 141.4m/s
Explanation:
The kinetic energy is energy due to the motion of a body
In this Case the kinetic energy of the turbine is given as
KE=1/2mv²
Where KE= kinetic energy
m= mass of water
v= velocity of the water
Data given
KE=10000j
m=1000g------kg =1000/1000= 1kg
v=?
Substituting our data into the expression we have
10,000=1/2(1*v²)
10,000=v²/2
Solving for v we have
v²=20,000
v=√20,000
v=141.4m/s
Answer:
v = 141.42 m/s
Explanation:
Mass of the water, M = 1000g = 1 kg
Kinetic energy of the turbine, KE = 10000 J
The speed of the water, v = ?
KE = 0.5 Mv²
10000 = 0.5 * 1 * v²
v² = 10000/0.5
v² = 20000
v = √20000
v = 141.42 m/s
