1750g of air performs an expansion work of 3100kJ on the surrounding as it expands horizontally to a pressure of 63000 kPa and a volume of 0.065 cubic meters. Find the temperature of air and its initial volume
A vertical cylinder fitted with a piston contains air initially at 120kPa and 100C. The piston is restrained by a set of stops. The piston diameter is 0.1m, its mass is 5kg, and the ambient pressure and temperature are 100kPa and 20C. The cylinder is..
a gravimetric analysis of atmospheric air results in approximately 23.15 oxygen and 76.85 nitrogen. what is the partial
A diesel engine is fitted with a turbocharger that comprises a radial flow compressor driven by a radial flow exhaust gas turbine. The gravimetric air-fuel ratio is 20:1; the air is drawn into the compressor at a pressure of 1 bar and at a temperatur..
An adiabatic constant-volume combustion chamber is filled with a mixture of air and methane; lambda (AFR/AFRs) = 1.3. The initial temperature of the mixture is 25°C, and its pressure is 1 bar. After laminar combustion from a single ignition source (a..
A counter flow cooling tower cools 2000 gal/min water from 104 F to 85 F with 210,000 ft^3/min of air at 90 F Dry bulb Temperature and 76 F WBT . The Mass transfer coefficient -surface area product is hA= 123lbm/hr ft^3. Air mass flow rate per unit c..
the light right-angle boom which supports the 400-kg cylinder is supported by three cables and a ball-and-socket joint O attached to the vertical x-y surface. Determine the reactions at O and the cable tensions.
the golf ball is hit at a with speed of v40ms and directed at an angle of 30 degrees with the horizontal. determine the
How many parts should be made in each mold for each quantity in part a and plot the cost over quantity on a semi-log plot.
A new liquid fuel with formula CHz is proposed for use in spark-ignition engines. To determine the fuel properties, a sample of fuel at 25 degress C was placed in a constant volume bomb calorimeter. Oxygen at 25 degress C was admitted to the bomb and..
water behind a dam enters an intake pipe at 24psia 5 fts flow through a turbine and exits 200ft below at 19psia 45 fts
air at 800 kpa and 400oc enters a steady-flow nozzle with a low velocity and leaves at 100 kpa. if the air undergoes an
A piston-cylinder assembly with an initial volume of 0.01m^3 is filled with saturated refrigerant 134a vapor at 16 degrees Celsius. The substance is compressed until a state of 9 bars and 60 degrees Celsius is reached. During the compression process,..
