Options
- A. K_1=K_2
- B. 2 K_1=K_2
- C. K_1 _2
- D. K_1 K_2
Answer
C. K_1 _2
Step-by-step solution
According to Bernoulli's principle, Kinetic energy per unit volume + Potential energy per unit volume + Pressure = Constant 1 2 V^2+ g h+P= constant Apply Bernoulli's principle at point X and Y, P+K_1+ g(0)=P+K_2+ g( ~h ) K_1=K_2+ g h K_1 _2
