Steam at 2100 kPa and 533.15 K (260°C) expands at constant enthalpy (as in a throttling process) to 125 kPa. What is the temperature of the steam in its final state and what is its entropy change? What would be the final temperature and entropy change for an ideal gas?
A man comes home on a summer day and finds that his house is at 35oC. He turns on the air conditioner. In 30 minutes the entire house is at 22oC. If the COP of the air conditioner is 2.8, calculate the powerthat must be supplied to it. Assume the..
What range of flow rates can be achieved if the valve can be throttled down to quarter open? When the valve is quarter open, what fraction of the pump work is lost across the valve?
5. A patient is placed on a kidney dialysis unit three times a week. The dialyzer has a membrane area of 1 m2 and is operated in a countercurrent mode. The blood flow rate is 200 ml/min and the dialysate flow rate is 500 ml/min. Membrane permeability..
Which of the following is insensitive to changes in pressure ?
Terminal voltage on the high-voltage side when the transformer is delivering full load at 230 V and 0.866 power factor lagging.
The armature-circuit resistance is 0.25 Ω and the series-field resistance is 0.25 ?4. Calculate the speed of the motor
Assume you. have a photodctcctor with a current rcsponsi vity of 5 AJW. A continuous wave HeNe laser with wavelength of 632.8 nm and spot size of 0.5 mm2 is incident on the active area of the detector. Assume that 6.37 x 1021 photons per m..
Derive an expression similar to Eq. (56) for finding the optimum exit temperature of cooling water from a heat exchanger when the temperature of the material being cooled is not constant.
If one of the machines has its field excitation adjusted such that it delivers 125 A lagging current, determine the armature current, power factor, excitation voltage, and power angle of each machine.
Find the value of Ia for which the generator efficiency is a maximum.
What are the advantages of external recruiting?
Example introduced a heat exchange system revamp problem. If the plate heat exchanger E101 in Figure 2.19 is the gasketed-plate type, then the exchanger area can be increased by adding plates to the exchanger. How much additional area must be adde..
