Find the flows and fluxes of exergy in the condenser of Problem 9.29. Use them to determine the second law efficiency, T0 = 15?C.
Problem 9.29
A coal-fired power plant produces 25 kg/s steam at 3 MPa, 600?C in the boiler. It cools the condenser with ocean water coming in at 15?C and returned at 18?C, so the condenser exit is at 50?C. Find the net power output and the required mass flow rate of ocean water.
The total gas volume that flowed through the dry gas meter was 2.785 cubic meters (at T = 60 deg F and P = 800 mm Hg). The mass of PM (particulate matter) was 1.50 g. Also, 72.0 g of H20 was collected in impingers.
If a mortar is proportioned to 0.11 ft3 of cement, 0,03 ft3 of lime, 0.27 ft3 of water, and 0.50 ft3 of sand, the percent voids in the sand is? (Assume a sand Bulk Specific Gravity Oven-dry of 2.60; of cement 3.15, and lime 2.25 if needed).
A perfectly mixed aeration pond with no recycle serves as the biological reactor for a small community. The pond receives 30m^3/d of influent with a BOD5 of 350mg/L that must be reduced to 20mg/L before discharge.
A company near City X want's to know how much benzene they can release into River Y. City Z is 85.5 miles downstream from City X. City Z doesn't want to have Benzene levels higher than 0.0000015 g/L.
A flow of 125,000 gallons per day enters a sedimentation basin which is 20 feet wide, 60 feet long and 12 feet deep. What is the minimum settling velocity of a particles that will be 100% removed by the basin
Three reservoirs - connected by a branching cast-iron pipe system. If the pipe lengths ar L1 = 3000ft, L2 = 2200, and L3 = 1600 ft the respective pipe diameters are 15,10, and 18in, and the surface water elevations of two of the three reservoirs are ..
Diameter of the hose and the nozzle are .25ft and .1ft respectively. If the pressure inside the hose is 60 psig and the flowrate is 1.2 ft^3/s, calculate the horizontal force required to hold the hose in place.
Suppose you are a member of an EPA enforcement team investigating the possible dumping of arsenic into Arbor Lake. You take water samples from the middle of the lake and find that the concentration is 90.0 ppb.
Two vessels are connected to a differential manometer using mercury (s=13.56), the connecting tubing being filled with water. The higher-pressure vessel is 5 ft lower in elevation than the other
A 2.25 Adisk spins within an oil-filled enclosure,having 2.4-mm clearance from flatsurfaces each side of the disk. The disk surface extends from radius 12 to 86 mm.What torque is required to drive the disk at 660 rpm if the oil's absoluteviscosity is..
At that time, the rocket has reached an altitude of 500 m and is rising at a velocity of 125 m/s. Gravity then takes over. The height of the rocket as a function of time is Create a function called height that accepts time as an input and returns..
Niagra falls measures 160 feet in height. Based on reasonable assumptions estimate the change in entropy for the water from the top of the falls to the bottom in kJ/kg*K.
