The velocity of the water jet discharging from the orifice can be obtained from v=\12ih, where h = 2 m is the depth of the orifice from the water surface. Determine the time for a particle of water leaving the orifice to reach point B and the horizontal distance x where it hits from surface.

Answers

The time for a particle of water leaving this orifice to reach point B and the horizontal distance are 0.553 seconds and 3.46 meters respectively.

How to calculate the time?

First of all, we would determine the velocity of the water jet discharging from the orifice by using this formula:

V = √(2gh)

V = √(2 × 9.81 × 2)

V = 6.264 m/s.

Next, we would determine the time taken to reach point B as follows:

S = Sa + Uy(t) + ½at²

-1.5 = 0 + 0(t) + ½ × (-9.81) × t²

t = 0.553 seconds.

Now, we can determine the horizontal distance:

Assuming saturated fluid is entering the value at point (3),

using table of R-134a properties
