Steam at 800 kPa, 350?C, flows through a convergent-divergent nozzle that has a throat area of 350 mm2. The pressure at the exit plane is 150 kPa, and the exit velocity is 800 m/s. The flow from the nozzle entrance to the throat is reversible and adiabatic. Determine the exit area of the nozzle, the overall nozzle efficiency, and the entropy generation in the process.
Find the mass flow rate, assuming compressible adiabatic flow. Repeat this calculation for incompressible flow
The low pressure steam must be condensed and pumped back to called the Rankine Cycle. we will explore the effects of pressure and temperature on the plant efficiency and take into account moisture in the turbine.
Determine the horizontal spacing of the vertical drains if the drains are installed in triangular grid to reach 90% of primary consolidation in 1.5 years after the commencement of fill placement.
A 10 m long built-up beam is to be fabricated from a universal section beam (UB) and two 'C' channel sections (as indicated). The beams are joined by bolts, with the allowable shear load in each bolt being 12 kN.
Determine the horizontal reaction that is developed on the gate at C.
Discuss how the experiment will be conducted, what measurements need to be taken, and how the specific heats will be determined. What are the sources of error in your system? How can you minimize the experimental error?iment complete
Set up a table showing curve elevations at the PVC, at the PVT, and at the half-station points along the curve. Compute the station and elevation of the curve turning point.
A heat engine operating in an environment at 298 K produces 5 kW of power output with a first law efficiency of 50%. It has a second-law efficiency of 80% and TL = 310 K. Find all the energy and exergy transfers in and out.
Geometric design and construction of a new two-lane two-way road has been recently completed and now it is time for design pavement near Ballarat, Victoria.
A carbon steel tank, 6ft. inside diameter X 10 ft. long with a 3/8 inch wall, is sitting on evenly spaced rolls and 4 evenly spaced supports (2 on each side). What is the horizontal force excerted on the supports
A flat broad-crested regular step dam with a drop of 2 m is situated on a grossly polluted stretch of river below a sewage outfall plant. The river is located at an elevation of 2 km.
A tow truck is using a cable to pull a car up a 15 degree hill. If the car weighs 4000 lbs and the cable has a diameter of .75 inches, find the stress in the cable when the truck comes to a stop while on the hill.
