Consider the power plant in Problem 9.41. Assume that the high temperature source is a flow of liquid water at 120?C into a heat exchanger at constant pressure, 300 kPa and that the water leaves at 90?C. Assume that the condenser rejects heat to the ambient, which is at -20?C. List all the places that have entropy generation and find the entropy generated in the boiler heat exchanger per kilogram of ammonia flowing.
Problem 9.41
A power plant for a polar expedition uses ammonia and the boiler exit is 80?C, 1000 kPa, and the condenser operates at -15?C. A single open FWH operates at 400 kPa with an exit state of saturated liquid. Find the mass fraction extracted in the turbine.
Bridge scour, Determine the magnitude of the contraction scour depth given the following information about the channel and bridge
a delivery company accepts only rectangular boxes the sum of whose length and girth (perimeter of a cross section) are equal to 108cm. find the dimensions of an acceptable box of a largest area.
A 45-cm-thick, 300-cm-high lightweight concrete masonry unit wall lies on a 20-cm-thick lightweight plain concrete slab. The 20-cm wide slab is supported by a reinforced concrete beam, which is placed on top of two columns (simply supported beam).
An electrostatic precipitator (ESP) is being designed to collect flue gas particles at a power plant. The following information has been collected: electric field intensity = 100,000 V/m, and average particle charge = 0.30 fC (1 fC = 10-15 C).
Assume the vertical reaction F at this end acts in the center and on the edge of the bracket as shown.
List some of the advantages and disadvantages of rectangular primary sedimentation tanks over circular sedimentation tanks which must be considered prior to the selection.
