Water is stored in an elevated reservoir. To generate power, water flows from this reservoir down through a large conduit to a turbine and then through a similar-sized conduit. At a point in the conduit 89.5 m above the turbine, the pressure is 172.4 kPa, ans at a level 5 m below the turbine, the pressure is 89.6 kPa. The water flow rate is 0.800 m3/s. The output of the shaft of the turbine is 658 kW.The water density is 1000 kg/m3. If the efficiency of the turbine in converting the mechanical energy given up by the fluid to the turbine shaft is 89% (nt = 0.89), calculate the friction loss in the turbine in J/kg.
Plot the lift and drag forces exerted on an airfoil as a function of velocity. Use velocity values going from 0 to 45 m/s on a log-linear plot (log-scale on the y axis).
Write a paper on Boyle's law and describe Compression and Combustion stroke . Also explain Charles's law and illustrate SI engine and CI engine.
Evaluate the valve closure to achieve a water exit velocity
this would provide you with a set of Reynolds numbers. Next, using the integral method, determine the velocity profiles within the boundary layer to be followed by determination of the heat transfer coefficient values for your selected Reynolds numbe..
A heat pump is used to maintain a house at a constant temperature of 23 °C. The house is losing heat to the outside air through the walls and the windows at a rate of 60,000 kJ/hr while the energy generated within the house from people
Determine the failure envelope and the non-failure region in the sigma_y - tau_xy plane using Tsai-Hill theory for the following cases
The 50-lb load is hoisted by the pulley system and motor M. If the crate starts from rest and by constant acceleration attains a speed of 15 ft/s after rising s = 6 ft, determine the power that must be supplied to the motor at this instant.
What are the design implications for the location and positioning of solar cells? Explain why the use of solar cells might be more appropriate in some regions of the country.
Determine the Final Velocity, An object whose mass is 1 lb has a velocity of 100 ft/s. How would I determine the final velocity, in ft/s, if the kinetic energy of the object decreases
Refrigerant R-134a vapor in a piston-cylinder assembly undergoes a constant-pressure process from saturated vapor at 800 kPa to 50 ºC.
In flows past solid bodies, the force exerted on the body by the fluid motion depends upon the fluid velocity u, the density p, the viscosity
A power outage occurred at a water distribution pump station. Before the power outage the station was pumping with one pump at 6,000 gpm in a 18" diameter Steel Pipe
