What is the dynamic viscosity of a fluid?
What is the dynamic viscosity of a fluid?
- The property of a fluid that resists the force tending to cause the fluid to flow
- The ratio of the shearing stress to the velocity gradient (correct)
- The force per unit area required to maintain a unit difference in velocity between two parallel layers of fluid
- The measure of the fluid's resistance to shear or tensile stress
What is the specific weight of a fluid?
What is the specific weight of a fluid?
- The ratio of the mass density of the fluid to the acceleration due to gravity
- The weight per unit volume of the fluid (correct)
- The measure of the fluid's resistance to shear or tensile stress
- The force per unit area required to maintain a unit difference in velocity between two parallel layers of fluid
What is the difference between an impulse turbine and a reaction turbine?
What is the difference between an impulse turbine and a reaction turbine?
- Impulse turbines operate at atmospheric pressure while reaction turbines operate at high pressures
- Impulse turbines are suitable for high head, low discharge while reaction turbines are suitable for low head, high discharge (correct)
- Impulse turbines convert kinetic energy into pressure energy while reaction turbines convert pressure energy into kinetic energy
- Impulse turbines have fixed nozzles while reaction turbines have moving nozzles
