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 horizontal circular cylinder of diameter d 0.2m and length 2m is elastically mounted on two springs and towing tank
What is the force P to keep the system in equilibrium for the angles specified?
Cantilever Beam with maximum tensile strength. A cantilever beam is to be made using a symmetrical I section beam. The cantilever is to carry a load of 40kN at a distance 2.5m from the fixed end. The situation allows for a depth of I beam to be no..
Determine the acceleration of the cabinet when sA = 40 ft. Note that when sB = 0, sA = 0 (points A and B are coincident).
An ideal vapor-compression refrigeration system operates at steady state with Refrigerant 134a as the working fluid. Superheated vapor enters the compressor at 30 lbf/in2, 20F, and saturated liquid leaves the condenser at 140 lbf/in2. The refriger..
