One kilogram of air as an ideal gas executes a Carnot power cycle having a thermal efficiency 50%. The heat transfer to the air during isothermal expansion is 50 kJ. At the end of the isothermal expansion, the pressure is 574 kPa and the volume is 0.3 m3. Determinea. The maximum and minimum temperatures for the cycle, in Kb. The pressure and volume at the beginning of the isothermal expansion in kPa and m3.c. The work and heat transfer for each of the four processes in kJd. Sketch the cycle on P-v coordinates
two spinning discs have the same angular momentum, but disk 1 has more kinetic energy than disk 2. Which one has the bigger moment of inertia - explain your reasoning?
Design the pump power and the diameter of brunching pipes D1, D2, D3, so that the flow rate coming into all buildings are Q1=Q2=Q3=4.5m^3/hr, when all four valves v, V1, V2, V3 are open.
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 temperature at which the liquid in the tank is completely vaporized. Also show the process on a T-v diagram with respect to saturation lines.
Describe the machinability evaluation criteria, is it a quantitative or qualitative evaluation and describe the High Speed Machining of Steel/Iron or Aluminium
A 0.7-lb block rests on top of a 0.5-lb block supported by but not attached to a spring of constant 9 lb/ft. The upper block is suddenly removed. Determine (a) the Maximum velocity reached by the 0.5-lb block, (b) the maximum height reached by the..
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
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.
you are given a task of compressing a fixed quantity of gas from P1,T1 to P2,T1. you wish to do this using a polytropic process coupled with a constant pressure P2 heat-transfer process. determine the polytropic process that minimizes the entropy ..
