In a reaction turbine, when steam flows through the fixed blades,
pressure increases while velocity decreases
pressure decreases while velocity increases
pressure and velocity both decreases
pressure and velocity both increases
✅ The correct answer is option B.
A body of weight W is required to move up on rough inclined plane whose angle of inclination with the horizontal is α. The effort applied parallel to the plane is given by(where μ = tanφ = Coefficient of friction between the plane and the body.)
P = W tanα
P = W tan(α + φ)
P = W (sinα + μcosα)
P = W (cosα + μsinα)
