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.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
