Which device is used to increase the pressure?
A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume.
How can we increase pressure of fluid?
Liquids and Gases: Fluids The pressure exerted by the gas can be increased by: increasing the number of collisions of gas molecules per unit time by increasing the number of gas molecules; increasing the kinetic energy of the gas by increasing the temperature; or decreasing the volume of the container.
What type of equipment is used to increase the pressure of liquids?
Pumps. Pumps do work on fluids, causing them to increase in pressure at a constant volume, due to the assumption that liquids that enter pumps are mostly incompressible.
Which device is use to increase velocity and decrease the pressure?
Diffuser
A diffuser is “a device for reducing the velocity and increasing the static pressure of a fluid passing through a system”.
What device increases water temperature?
Explanation: Superheater: A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam.
How does pressure affect fluids?
Liquids are relatively incompressible because any increase in pressure can only slightly reduce the distance between the closely packed molecules. If the pressure above a liquid is increased sufficiently, the liquid forms a solid. If the pressure above a liquid is decreased sufficiently, the liquid forms a gas.
Which of the pump is a mechanical device to increase the?
Centrifugal pump
A Centrifugal pump is a mechanical device that is used to increase the pressure of the fluid. Pressure rise of the fluid happened though imparting the prime mover energy to the impeller of the pump.
What is liquid pressure in construction?
In fact, a fluid pushes perpendicularly (outward) against any surface that contains it. This pushing outward by the water against the drum surface is called pressure. Fluid pressure increases with depth.
What are nozzles used for?
A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them.
What is convergent nozzle?
A convergent nozzle is a nozzle that starts big and gets smaller-a decrease in cross-sectional area. As a fluid enters the smaller cross-section, it has to speed up due to the conservation of mass. To maintain a constant amount of fluid moving through the restricted portion of the nozzle, the fluid must move faster.
