Document Summary

4. 29 refrigerant 134a flows at steady state through a horizontal tube having an inside diameter of 0. 05 m. the refrigerant enters the tube with a quality of 0. 1, temperature of 36oc, and velocity of 10 m/s. The refrigerant exits the tube at 9 bar as a saturated liquid. Determine (a) the mass flow rate of the refrigerant, in kg/s. (b) the velocity of the refrigerant at the exit, in m/s. (b) the rate of heat transfer, in kw, and its associated direction with respect to the refrigerant. Engineering model: the control volume shown with the schematic is at steady state, for the control volume, Analysis: (a) mass flow rate at the inlet is m. Specific volume of the refrigerant at the inlet is determined using quality v1 = vf1 + x1(vg1 vf1) From table a-10 at t1 = 36oc, vf1 = 0. 0008590 m3/kg and vg1 = 0. 0223 m3/kg.

Read the passage from "The Beginnings of the Maasat"

Neiterkob was confused at first. It was one thing for an eruption to send cows flying up into the sky, but it was another problem entirely to get them down to earth again. The wise god knew how to solve the problem. Enkai grew a giant fig tree out on the plains The tree grew rapidly, and its branches grew so high that they reached up into the heavens. One by one, Enkai sent the cattle walking down branches of the fig tree, all the way down to the roots at the ground. My father and our people accepted the cattle and began to herd them with the sticks that Enkai had given us Now, the rest of the tribe calls my father the "Beginner of the Earth" because he mediates between Enkai and our tribe, just as he did when the cattle returned from the sky

A regenerative gas turbine power plant is
shown in Fig. P1. Air enters the compressor at 1
bar, 27ºC with a mass flow rate of 0.562 kg/s and
is compressed to 4 bar. The isentropic efficiency of
the compressor is 80%, and the regenerator
effectiveness is 90%. All the power developed by
the high-pressure turbine is used to run the
compressor. The low-pressure turbine provides the
net power output. Each turbine has an isentropic
efficiency of 87% and the temperature at the inlet
to the high-pressure turbine is 1200 K. Sketch the
corresponding T – s diagram and determine: (a) The net power output, in kW. (b) The thermal
efficiency. (c) The temperature of the air at states
2, 3, 5, 6, and 7, in K.
