1. A heat engine receives 1 kW heat transfer at 1000 K and gives out 400 Was work, with the rest as heat transfer to the ambient at 25?C. What are the fluxes of exergy in and out?
2. In a refrigerator, 1 kW is removed from the -10?C cold space and 1.3 kW is moved into the 30?C warm space. Find the exergy fluxes, including the direction associated with the two heat transfers.
The beam is fully restrained at both ends but is unbraced along its span. Determine the maximum magnitude of PQ that satisfies the ultimate strength limit state for flexural strength

differential leveling between benchmarks A,B,C,D, and A gives elevation differences(m) of -15.632, 32.458, 38.214, and -55.025, and distances(km) of 4,6,5, and 3 respectively.
The country town with service area of 150 ha is sewered, and the main outfall sewer is laid on a grade (slope) of 0.003 m/m to a treatment plant. Effluent from the treatment plant is at present discharged via an open channel to the river.
Water is pumped 9 mi from a reservoir at elevation 100 ft to a second reservoir at elevation 210 ft. The pipeline connecting the reservoirs has a 54-in diameter. It is concrete and has an absolute roughness of 0.003. If the flow is 25 mgd and pumping..
On the basis of the velocity distribution in the inner wall region, justify the Pitot-Prandtl-Preston tube's method.
A spherical tank is being designed to hold 7 moles of methane gas at a pressure of 8 bar and a temperature of 50oF. Determine the volume of the spherical tank to be used.
LANDSAT as a spatial resolution of 15m and an altitude of 700km. IKONOS has a spatial resolution of 1m and an altitude of 680km. Calculate the IFOV corresponding to the spatial resolution for sensor.
The man has a mass of 75 kg, and the beam has a mass of 40 kg. The beam is in equilibrium with the man standing at the end and pulling on the cable. Determine the force exerted on the cable by the man and the reactions at pinned support C.
A key part of the FEM and any FEA model are the appropriate assignment of boundary conditions. Explain why it is necessary to set the appropriate boundary conditions in FEA simulations. What happens if you don't assign boundary conditions or assig..
A steel tank with 2.5 m high vertical walls and a flat triangular floor is filled with three immiscible liquids layered upon each other. Two of the walls are 1.2 m long and perpendicular to each other. There is one tonne of water in the tank, a dep..
