✅ The correct answer is option A.
Discharge (Q) of a centrifugal pump is given by (where D = Diameter of impeller at inlet, b = Width of impeller at inlet, and Vf = Velocity of flow at inlet)
Q = π.D.Vf
Q = π.b.Vf
Q = π.D.b.Vf
Q = D.b.Vf
✅ The correct answer is option C.
The tractive force in a locomotive with two cylinders is given by (where c = Fraction of reciprocating parts per cylinder, m = Mass of reciprocating parts, ω = Angular speed of crank, r = Radius of crank, and θ = Angle of inclination of crank to the line of stroke)
m.ω2.r cos θ
c.m.ω2.r sin θ
(1 – c)m.ω2.r(cos θ – sin θ)
m.ω2.r(cos θ – sin θ)
