A centrifugal pump running at 900 rpm has an impeller diameter of 500mm and eye diameter of 200 mm. The blade angle at outlet is 35° with the tangent. Determineassuming zero whirl at inlet, the inlet blade angle. Also calculate the absolute velocityat outlet and its angle with the tangent. The flow velocity is constant at 3 m/s. Also calculate the manometric head.
Tensile force formulas, A cylindrical steel beam is 2 inches diameter and 6 feet long. The modulus of elasticity is 30 x 1,000,000 psi. If the beam is subjected to a tensile force of 1000 lbs, what will be the resulting unit strain?
