An air standard dual-combustion cycle has a mean effective pressure of 10 bar. The minimum pressure and temperature are I bar and 17°C respectively, and the compression ratio is 16/1. Calculate the maximum cycle temperature when the cycle efficiency is 60%. The maximum cycle pressure is 60 bar.
how many lbf does it take for a 4.0 x 103 lbm car to achieve 0 to 60 mph in 10. seconds? use fma where a is

a small steel cylinder is used as a pressure vessel for a paint gun. the label says 24 grams co2 filled. assume the
A gas in a piston-cylinder assembly undergoes an expansion process for which the relationship between pressure and volume is given by pV^n = constant. The initial pressure is 4.25 bar, the initial volume is 0.25 m^3 and the final volume is 0.55 m^3 .
Knowing that the thin cylindrical shell shown is of mass m, thickness t, and height h, determine the mass moment of inertia of the shell with respect to the x axis
Sketch the corresponding curves in the z and w planes, indicating the region onto which the interior of the circle in the z plane is mapped.
As you stroll the isles of the local flea market, you come across a booth stocked with surplus permanent magnet brushed DC motors. Your eyes widen with excitement as you notice a particularly shiny gear motor priced at just $1.50. Whipping your trust..
A turbine receives air at 1500 K, 1000 kPa and expands it to 100 kPa. The turbine has an isentropic efficiency of 85%. Find the actual turbine exit air temperature and the specific entropy increase in the actual turbine.
Plot the engineering stress-strain curve. Determine i. Young's modulus, ii. the 0.2% offset yield strength, iii. the tensile strength, iv. the percent elongation, and v. the percent reduction of area.
How much work(J)is done in a natural rubber filament when strains slowly and non reversely to a= 2?
Calculate the Grashof number using Equation 9.65, which can be applied to natural convection flows driven by temperature and concentration gradients. Use a characteristic length L that is appropriate for the exposed surface of the water bath.
An ideal gas is confined to one side of a rigid, insulated container divided into equal volumes by a partition. The other side is initially evacuated. The following data are known for initial state of the gas: p1 = 300 kPa, T1 = 380K and V1 = 0.025 m..
