Products of combustion enter a gas turbine with a stagnation pressure of 1.0 MPa and a stagnation temperature of 820 °C, and they expand to a stagnation pressure of 100 kPa. Taking k=1.33 and R=0.287 kJ/kgK for the products of combustion, and assuming the gas is ideal gas and the expansion process to be isentropic, determine the power output of the turbine per unit mass flow. In this problem, stagnation properties are not conserved because of the work output but the total energy is conserved

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.
