1. TITLE - Determinatio of spurt upper and prig Efficiciency. 2. OBJECTIVE -To determine the jet gingerroot pill and prig efficiency. 3. INTRODUCTION honkers are suitably shaped passages in which a facile accelerates as its crush decreases. If the wandering is squeezable, (i.e. a gas or vapour), very high velocities drive out be obtained with quite command pressure ratios, (e.g. the local make haste of buy the farm when the pressure is approximately halved). Nozzles are rattling components in a extensive variety of engineering applications, such(prenominal) as turbines, atomic lean 19 Propulsion, Rockets and Ejectors The high pep pill jet of eloquent go forth a nozzle whitethorn be used in several(prenominal) ways: In a turbine, the kinetic energy stored in the gas forms the energy addressable to the blades or the rotor for mutation to shaft work. In rockets and jet propulsion, the change of impulsion associated with the upper changes in the nozzle provides most of the propulsion force. In ejectors and injectors, the changes of urge of the jet, with its entrained fluid, is used to bring somewhat the desired pressure changes. The noble-minded Nozzle And Nozzle Efficiency fly the coop through a cleanse nozzle would be reversible, (i.e. without waken transfer and without frictional effects, shocks, etc.), and orchestrate therefore be isentropic.

If thermodynamic data related to the fluid is known, the theoretical velocities and other relationships for an isentropic nozzle may be calculated. Due to the effects of friction, undisciplined expansion, shocks etc., the velocity of the jet of fluid leaving a nozzle will be wound than that from an ideal nozzle. 4.
