Answer:
The velocities in points A and B are 1.9 and 7.63 m/s respectively. The Pressure at point B is 28 Kpa.
Explanation:
Assuming the fluid to be incompressible we can apply for the continuity equation for fluids:
Where A, V and Q are the areas, velocities and volume rate respectively. For section A and B the areas are:
Using the volume rate:
Assuming no losses, the energy equation for fluids can be written as:
Here P, V, p, z and g represent the pressure, velocities, height and gravity acceleration. Considering the zero height level at point A and solving for Pb:
Knowing the manometric pressure in point A of 70kPa, the height at point B of 1.5 meters, the density of water of 1000 kg/m^3 and the velocities calculated, the pressure at B results:
Answer:
Explanation:
We understand that the sum of the pressures in the tank and the pump is equal to that of the Nozzle,
In this way,
For the pressure we also know that it is given by
So,
