Answer:
The overview of the given scenario is explained in explanation segment below.
Explanation:
- The inception of cavitation, that further sets the restriction for high-pressure and high-free operation, has always been the matter of substantial experimental study over the last few generations.
- Cavitation inception would be expected to vary on the segment where the local "PL" pressure mostly on segment keeps falling to that are below the "Pv" vapor pressure of the fluid and therefore could be anticipated from either the apportionment of the pressure.
⇒ A cavitation number is denoted by "σ" .
Answer:
HV = 372.4 KGf/mm^2
Explanation:
given data:
minimum tensile strength = 1240 MPa
we knwo that 
and brinell hardness number (HB} relation given as
1) relation betwen H.B and Rockwell is
2) relation between HB and Vickers hardnes HV is given as
HV = 372.4 KGf/mm^2
Answer:
Tmax = 2.934ksi
φ = 4.58°
Explanation:
Given.
Length = 100 ft
Maximum power = 2590 hp
Angular rotate = 1700 rpm .
Outer diameter of the shaft = 8 in. Wall thickness = 3/8 in.
Calculating angular velocity.
= 1700rev/min * 2πrad/rev * 1min/60s
= 56.67πrad/s
Convert power to ft.lb/s
2590hp = 2590 * 550
= 1424500ft.lb/s
At this point, we calculate torque.
Torque = Power/Angular Velocity
Torque = 1424500/56.67π
Torque = 8000.24lb.ft
Using the torsion formula, we'll calculate maximum stress due to the shear force acting on the body:
Tmax = ½(Tc/J)
Tmax =½ of (8001.24 * 12 * 4 )/ (π/4)(4⁴ - 3.625⁴)
Tmax = ½ * 5868.656298363693
Tmax = 2934.328149181846
Tmax = 2.934ksi
Calculating the angle twist
φ = TL/JG
φ = (8001.24 * 12 * 100 * 12 )/( (π/4)(4⁴ - 3.625⁴)(4⁴ - 3.625⁴)(11)(10^6))
φ = 0.08002 rad -- convert to degrees
φ = 4.58° --- approximated
Answer: Cultural Issues and the Human-Made Environment. Mass production and related machine techniques in construction and servicing also dictate a multitude.
