Answer:
Water enters a centrifugal pump axially at atmospheric pressure at a rate of 0.12 m3/s and at a velocity of 7 m/s, and leaves in the normal direction along the pump casing, as shown in Fig. PI3-39. Determine the force acting on the shaft (which is also the force acting on the bearing of the shaft) in the axial direction.
Step-by-step solution:
Step 1 of 5
Given data:-
The velocity of water is .
The water flow rate is.

Explanation:
Diagrams of Shear force show the total shear force at each cross section of a structural member throughout the length of the beam or structural member. However, that force is not equally distributed throughout the individual cross section of the structural member. The maximum shear stress is referred to as the maximum concentrated shear force in a small area.
The Maximum Shear Stress theory states that failure occurs when the
maximum shear stress from the total of principal stresses equals
or exceeds the value obtained for the shear stress at yielding in the
uniaxial tensile test.
At yielding, in an uni-axial test, the principal stresses is given as:
σ=Sy; -
σ2 = 0 and σ3 = 0.
Therefore the shear strength at yielding
Ssy =[σ- (σ2 or σ3=0)]/2. Therefore Ssy = Sy/2
From the information given:
Tmax= σ1 - σ2/2
Tmax= 450-200/2
Tmax= 250/2
Tmax= 125 kpa
