A gas turbine Brayton cycle operates with an intercooler a re-heater and a regenerator. Air enters the engine at 14 psi and 60 °F; the pressure ratio for each stage of compression is 3; the air temperature when entering a turbine is 940 °F and the regenerator operates perfectly (effectiveness is 100%) Determine the mass flow rate of the air passing through this engine and the rates of heat addition and rejection when this engine produces 1000 hp. Assume constant specific heats at room temperature.
A cylindrical specimen of this alloy 24 mm in diameter and 186 mm long is to be pulled in tension. Calculate the force necessary to cause a 0.0119 mm reduction in diameter. Assume a value of 0.33 for Poisson's ratio.
Calculate the time rate of change dHB/dt of angular momentum about point B when the particle passes the bottom of the guide at C.
Finding exit velocity from air nozzle, Air enters a nozzle operating at steady state at 800 ºR with a negligible velocity and exits the nozzle at 570 ºR.
A piston-cylinder device contains 0.8kg of steam at 300 degrees C and 1 MPa. Steam is cooled at constant pressure until one-half of the mass condenses.
I would expect somthing like the requirement to execute the equation, please explain each term in the equation with its engineering units.
A 50 hp motor with an efficiency of 0.80 is to be replaced by a newer model motor with an efficiency of 0.90. The motor is expected to operate 3000 hours per year. The cost of electricity in our area is $0.06 per kWhr.
How is the technology utilized effectively or ineffectively? What are some barriers to more effective usage, and what are some recommendations you would make to overcome these barriers?
