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. And measuring the flow rate of water in different height outlets with

THE WORLD’S NUMBER ONE INJECTION HOSE SYSTEM FUKO is a specially designed and patented solid core PVC Injection Hose System which is installed in concrete joints to waterproof and seal any cracks or voids in the joint area. The FUKO System seals joints watertight and offers a complete maintenance program if leakage appears in the future. When Portland Cement‚ Microfine Cement‚ or Duroseal Injection Resins are selected‚ the FUKO System can be used for multiple re-injections – a significant advantage

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
