and then into the jacket-water circulating pumps. It is then pumped around the cylinder jackets‚ cylinder heads and turboblowers. The jacket cooling system is a closed circuit. Water passing from the engine returns through a cooler to the circulating pump and then to the engine. A header or expansion tank is placed at a sufficient height to allow the venting and water make-up in the system. This has connection from the engine discharge and to the pump suction line. A heater is included with by-pass

In this experiment‚ required equipment are a water tank‚ piezometric tubes‚ pump‚ a stop watch‚ empty bucket and a digital weight scale. By operating the pump to keep the water is full in the water tank‚ and measuring the height of water in the piezometric tubes in different height of water outlets.

PRE-LAB QUESTIONS 1. Define shut off head. Shut-off head is a condition‚ when a centrifugal pump runs with discharge valve closed. When a serviced pump is to be tested for its performance‚ we are running pump with different discharge condition to ensure that the pump is capable of performing as designed. Shut-off head is the maximum head generated by a centrifugal pump with zero flow and relatively less power. Because it has to overcome very small head[upto discharge valve]‚less frictional

Destin Brass Products Problem: - The Company is producing 3 major products – Valve‚ Pump and Flow Controller. The Company is concerned about the price cutting of Pumps going on in the market every month. It is also surprised to see no change in sales of Flow Controller despite 12 ½% increases in prices. Current Scenario: - Currently it is using traditional accounting system‚ Unit of product is charged for material cost‚ labor cost (standard time for labor times the labor pay rate $16 per hour)
