Firefighters are holding a nozzle at the end of a hose while trying to extinguish a fire. the nozzle exit diameter is 8 cm, and the water flow rate is 16 m3/min. take the density of water as 1000 kg/m3 and the momentum-flux correction factor as unity.

On a average work day more than work place firs are reorted

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
