- Discharge of a centrifugal pump is (where N = Speed of the pump impeller)
- A Pelton wheel working under a constant head and discharge, has maximum efficiency when the speed ratio is
- When a vertical wall is subjected to pressures due to liquid on both sides, the resultant pressure is the __________ of the two pressures.
- The speed of an imaginary turbine, identical with the given turbine, which will develop a unit power under a unit head, is known as
- The overall efficiency for a Pelton wheel lies between
- A vertical wall is subjected to a pressure due to one kind of liquid, on one of its sides. The total pressure on the wall per unit length is (where w = Specific weight of liquid, and H = Height of liquid)
- A liquid would wet the solid, if adhesion forces as compared to cohesion forces are
- Which of the following manometer has highest sensitivity?
- The viscosity of a liquid __________ its rate of flow through a hole in a vessel.
- A uniform body 3 m long, 2 m wide and 1 m deep floats in water. If the depth of immersion is 0.6 m, then the weight of the body is
