Pump Experiment

ET a Test rig consists of a Francis water turbine designed for laboratory experimental purpose and to conduct test in metric units. The specifications of the turbine are as follows: The unit consists of a cast iron spiral casing, a bearing pedestal, a rotor assembly of shaft, gunmetal runner and brake drum all mounted on a suitable sturdy base.

Aerofoil shaped gunmetal guide vanes are provided in the turbine to regulate the flow into the runner.

The guide vane opening adjustment is made through a hand wheel and a suitable link mechanism. A conical draught tube is connected to the turbine outlet by a bend.

For observing the flow at the runner exit, a transparent window made of thick perspex tube is provided in between the turbine casing and the draft bend. A rope brake arrangement with a set of dead weights and spring balance is provided for loading the turbine.

Pressure gauge and vacuum gauge are fixed at the inlet and outlet to measure the net supply head to the turbine. The pump operates on Volts, 3 Phase, 50 Hz line. The tank is provided with FRP lining for total rust protection Request.Centrifugal pumps – Sample Pump Curve • is the RPM • Impeller size 6¼ to 8¾ in.

Centrifugal pump experiment

Currently, science knows of precious few methods of simulating gravity on a spacecraft.. These boil down to: using acceleration by thrusting the ship, spinning the ship (or sections of the ship) to utilize "centrifugal force", or placing a large mass under the ship (generally by landing on a planet)..

These boil down to: using acceleration by thrusting the ship, spinning the ship (or sections of the ship) to utilize "centrifugal force", or placing a large mass under the ship (generally by landing on a planet).. Centrifugal force is the method of choice for obvious reasons. The history of hydraulic systems can be traced back to the , when Braise Pascal performed the first hydrostatic experiment. He used a Pascal’s barrel to investigate the effect of a force applied at one point of the fluid and how it is transmitted to the other sections within an enclosed system.

Centrifugal force is the method of choice for obvious reasons. Pumps typically have an inlet where the fluid (or air) enters the pump and an outlet where the fluid/air comes out.

The inlet location is said to be at the suction side of the pump. The outlet location is said to be at the discharge side of the pump.

HOW TO design a pump system

Operation of the pump creates suction (a lower pressure) at the suction side so that fluid/air can enter the pump through the inlet. One contemporary method which has been successful in widening the map is the ‘ported shroud’ feature. It moves the surge line to the left by allowing a small amount of airflow to bleed off the low-velocity portion of the wheel and recirculate, to ward off blade stall.
