Afeed water heater in a vapor power plant operates at steady state with liquid entering at inlet 1 with t1 = 45degreec and p1 = 3.0 bar - water vapor at t2 = 320degreec and 3.0 bar enters at inlet 2. saturated liquid water exits with a pressure of p3 = 3,0 bar. ignore heat transfer with the surroundings and all kinetic and potential energy effects, ii the mass flow rate of the liquid entering at inlet 1 is 3,2 times 105 kg/h, determine the mass flow rate at inlet 2, mh in kg/h.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater

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?

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
