Centrifugal pumps uses OF CENTRIFUGAL PUMPS: The applications of centrifugal pumps are numerous; however‚ these pumps are most often used in buildings for the following purposes: To pump the general water supply. This includes both the overhead and pneumatic tank systems. In general water supply systems where the pump takes off directly from the city pressure main or where no suction lift is required‚ a centrifugal pump can be used. When a centrifugal pump is being used with a suction

Originally developed from the water wheels‚ hydraulic turbines are the prime mortars of importance in modern water power development. According to their hydraulic action‚ turbines are broadly divided into two classes. (1) Impulse Turbine: Impulse turbines are more efficient for high heads

flow going through. An example of a Kaplan turbine can be seen in Figure 1. An example of an impulse turbine is the Pelton turbine. The Pelton turbine is ideal for lower flow‚ high head applications. Run by the force of a jet of water impacting it‚ the Pelton turbine is governed by Newton’s second law. As the jet of water hits the cup‚ the change in energy in imparted onto the wheel causing it to rotate. The direct impact of the water onto a flat surface of the turbine can create unwanted vibrations

HYDRAULIC TURBINES Meaning of the term ‘Hydraulic’ • The working fluid is a liquid or a gas?? ANSWER – WORKING FLUID IS A LIQUID. TURBINE – WORKING PRINCIPLE • In turbines the pressure energy is converted into mechanical energy(which is further converted into electrical energy). WORKING PRINCIPLE OF PUMPS it is just the reverse of the above‚ that is‚ the mechanical energy is converted into pressure energy. OUR FOCUS OF STUDY • Working of various types of hydraulic turbines.

Introduction Hama in Syria is famous for these water wheels‚ initially built by the Romans in what must be one of the most impressive engineering feats ever seen in a while. The current turns the wheels which contain small buckets which fill up with water and then spill out over to the aqueduct to its side... basically how to pump water from the river without using a pump. Apparently the wheels are all a-spin in the summer when there’s more water. History Norias were first developed in the Byzantine
