Asteam rankine cycle operates between the pressure limits of 1500 psia in the boiler and 6 psia in the condenser. the turbine inlet temperature is 800°f. the turbine isentropic efficiency is 90 percent, the pump losses are negligible, and the cycle is sized to produce 2500 kw of power. how much error is caused in the thermal efficiency if the power required by the pump were completely neglected

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Which from the following instrument is commonly used to detect the high pitch butzing sound in bearings? [clo4] a)-digital ultrasonic meter b)-infrared camera c)-spectroscopic d)-vibrometer
