Water enters a centrifugal pump axially at atmospheric pressure at a rate of 0.09 m3/s and at a velocity of 3 m/s, and it leaves

in the normal direction along the pump casing. Determine the force acting on the shaft (which is also the force acting on the bearing of the shaft) in the axial direction. Take the density of water to be 1000 kg/m3.

To develop this problem it is necessary to apply the concepts related to Mass Flow, as a unit dependent on density and volumetric flow rate, as well as apply the sum of Forces on the flow. We will start by determining the mass flow:

\dot{m} = \rho \dot{V}

Where,

\rho = Density of water

\dot{V} = Volumetric flow rate

Replacing our values we have

\dot{m} =1000*0.09

\dot{m} = 90Kg/s

Calculate the force acting on the shaft by using the moment equation for steady one-dimensional flow,

\sum \vec{F} = \sum \limit_{out} \beta \dot{m} \vec{V} - \sum_{in} \beta \dot{m} \vec{V}

(-F_R)_x = -\beta \dot{m}V

Where

\beta=momentum flux Correction factor

V = Velocity

Replacing we have then

\beta = 1

\dot{m} = 90kg/s

V = 3m/s

-(F_R)_x = (1\times 90\times 3)

(F_R)_x = 270N

Therefore the force acting on the shaft is 270N

a sponge and a bar of soap occupy the same amount of space, but the soap is much more dense than the sponge
Alex Ar [27]
Yes, that's correct.  That's a big part of the reason why
the soap floats in water and the sponge sinks in it.

Calculating the Mass of a Granite Monument
Volgvan

Answer:

m = 684,865,8 g

Step-by-step explanation

V = 25,365.4 cm^3            Is volume

r = 27g/cm^3                     Is density

To calculate mass you use formula:

m= V*r

m = 25,365.4 x 27

m = 684,865,8 g

In order to control bacterial infections and/or food poisoning, the FDA (Food and Drug Administration) has approved the use of n
Lelechka [254]

The answer is food irradiation. This involves the brief exposure of food to gamma rays or X-rays to kill pathogens that may contribute to food spoilage. This increases the shelf-life of the food. Gamma rays and X-rays emanate from nuclear decay of radioactive materials such as uranium..
