At what speed does the water exit the hole?

5.2 meters per second
Thus, the speed of the water coming out of the hole is 5.2 meters per second.

What happens to the flow rate when the diameter of the hole is increased?

No. The flow rate / discharge increases when diameter increases. For given pressure drop, mass density, and effective length, the square of the volumetric flow-rate, given by Bernoullis principle, is proportional to the diameter to the fifth divided by the friction factor.

Does water flow out of all the holes with the same speed and pressure?

The water coming out of a hole in the side of a can near the bottom comes out quickly because the water pressure near the hole is bigger than the air pressure outside of the hole, and so there is a net force on a little bit of water that’s passing through the hole.

At what speed must the water be flowing in the pipe?

What is a ‘good’ pipe velocity?

Fluid	Typical Pipe Velocity (m/s)
Water	0.9 – 2.4
Carbon tetrachloride	1.8
Chlorine, liquid	1.5
Ethylene glycol	1.8

Does hole size affect flow rate?

Our hypothesis was correct; our data shows that as the size of the diameter of the holes increases, the flow rate also increases. So even though the holes got smaller and smaller at a gradual, constant rate, the flow rate decreased at a rate that changes as the hole gets smaller.

Does diameter affect flow rate?

The diameter of pipe and flow rate: In a fluid passing through a pipe, a reduction in the diameter of the pipe can compress the flowing fluid. It flows faster, which increases the flow rate. And if the diameter increases, then the flow rate reduces.

How do you calculate speed of flow?

Q=Vt Q = V t , where V is the volume and t is the elapsed time. The SI unit for flow rate is m3/s, but a number of other units for Q are in common use. For example, the heart of a resting adult pumps blood at a rate of 5.00 liters per minute (L/min).

How do you calculate speed of water flow?

Find the surface water velocity (in m/s) by dividing the distance from AA to BB (in this example, 10 m) by the average time (in seconds) and multiply this result by 0.85 (a correction factor) to estimate the average water velocity of the stream. Average water velocity = 0.5 m/s x 0.85 = 0.425 m/s.

How do you calculate fluid speed?

We note that Q=V\t and the average speed is ¯v=d/t. Thus the equation becomes Q=A¯v. This is called the equation of continuity and is valid for any incompressible fluid.

Is water speed the same as land speed?

Speed over water is the distance traveled in one hour with respect to water. Similarly speed over ground is the distance traveled in one hour with respect to ground. Sea conditions are perfect with no wind and current and your ship’s GPS is showing speed of 15 knots.
