1. Consider an ideal steam reheat cycle in which the steam enters the high-pressure turbine at 600 lbf/in.2, 700 F and then expands to 150 lbf/in.2. It is then reheated to 700 F and expands to 2.225 lbf/ in.2 in the low-pressure turbine. Calculate the thermal efficiency of the cycle and the moisture content of the steam leaving the low-pressure turbine.
2. An open FWH receives steam at 150 psia, 400 F from the turbine and 1150 psia, 200 F water from the feed water line. Find the required fraction of the extraction flow in the turbine.
You have a stream of air containing methanol at 5% by volume. The stream is flowing at 2000 actual ft^3/min at 1 atm pressure and 110 F. The regulations require94% removal of the methanol, and you decide to try a water absorption column, using pure w..
CVE80010 - Principles of Sustainability - write a report that compares and contrasts how Energy sustainability and Water sustainability have been addressed in Australia in comparison to an overseas country of your choice.
A gate having the cross section is 4 ft wid and is hinged at C. The gate weighs 18,000 lb, and its mass center is 1.67 ft to the right of the plane BC. Determine the vertical reaction at A on the gate when the water level is 3 ft above the base.
The probability density function, f(t), of the time in hours between storms during the summer in Miami is estimated as f(t) = .014e^(-.014t) if x > 0, f(t) = 0 if x is less than or equal to 0 where t is the time interval between storms in hours.
Find the heat transfer out of the R-134a, the extra work input to the refrigerator due to this process, and the total irreversibility including that of the refrigerator.
Two level sections of an east highway (G=0) are to be connected. Currently, the two sections of highway are seperated by a 4000-ft (horizontal distance), 2% grade.
A 24-in.-wide by 0.100-in.-thick by 140-in.-long steel sheet is to be formed into a hollow section by being bent through 360° and having the long edges welded (i.e., butt-welded) together. Assume a cross-sectional medial length of 24 in.
The 35-in pump of fig. 11.7b is used to pump 24000 GPM of water (68ft) at 710 rpm from a large tank whose surface is at atmospheric presure. the head loss from tank to the pump inlet is 3ft.
Consider two identical rooms, one with a 2-kW electric resistance heater and the other with three couples fast dancing. In which room will the air temperature rise faster?
A temporary diversion has been constructed on a highway of +4 percent gradient due to major repairs that are being undertaken on a bridge. The maximum speed allowed on the diversion is 10 mph
