WebEXPERIMENT : DETERMINATION OF NOZZLE EFFICIENCY Introduction: Nozzles are suitably shaped passages in which a fluid accelerates as its pressure decreases. … WebNet Head. Net head is basically defined as the head available at the inlet of the turbine. Net head is also simply called as effective head. When water will flow from head race to the turbine, there will be some losses of head due to friction between water and penstock. There will also be other losses of head such as loss of head due to bend ...
WebCO 2 lasers have an efficiency of approximately 10%, therefore to power a 6kW laser, a 60kW power supply is needed whereas, a fiber laser cutter is approximately 45% (can be up to 50%) efficient so only a 13kW supply is needed. Clearly, as the laser power increases so will the electricity costs of the machine due to the need for a larger chiller. Web69. In a steam power plant, the function of a condenser is. (a) to maintain pressure below atmospheric to increase work output from the primemover. (b) to receive large volumes of steam exhausted from steam prime mover. (c) to condense large volumes of steam to water which may be used again in boiler. (d) all of the above.
