A piston-cylinder device contains products of combustion from the combustion of a hydrocarbon fuel with air. The combustion process results in a mixture that has the composition on a volume basis as follows: 4.89 percent carbon dioxide, 6.50 percent water vapor, 12.20 percent oxygen, and 76.41 percent nitrogen. This mixture is initially at 1800 K and 1 MPa and expands in an adiabatic, reversible process to 200 kPa. Determine the work done on the piston by the gas, in kJ/kg of mixture. Treat the water vapor as an ideal gas.
The flow out of a reservoir is 2 L/s. The reservoir surface is 5 m x 5 m. How fast is the reservoir surface dropping?
A rectangular shelf is attached to a wall by two brackets 12 inches apart at points A and B , as shown in Figure P10.17 . A wire with a 10-lbf weight attached to it is hanging from the edge of the shelf at point C . Determine the moment of force a..
Brine flood in a 1.9-in-long and 1.5-in-diameter core plug from the North Sea resulted in a stabilized pressure drop of 46.05 psi. The flood was carried out at 0.05 mL/min with brine viscosity of 0.443 cP. Determine the absolute permeability of this ..
The drag force (Fd) acting on a spherical particle that falls very slowly though a viscous fluid is a function of a particle diameter, d, the particle velocity, V, and the fluid viscosity, u. Using dimensional analysis determine the Pi term(s) suitab..
We have a small wood deck, 8' by 8' This deckshould only have a max of five adults on it. Oneside of deck is attached to the wall of the house, and out fromthis wall is two post six feet from the wall. Problem is the load bearing strength of the be..
The buses are run by independent drivers, however, who make no attempt to coordinate their schedules. Actually, one bus runs slightly faster than the other so that over many trips the fraction of trips that the second bus leaves within a time t
It is required to reduce a pipe of diameter 8 in to a minimum diameter pipe that allows the downstream velocity not to exceed twice the upstream velocity. Determine the diameter of the pipe. Assume smooth transition
You are given the following information about a dry-batchpaving operation. You are going to use one mixer that has a servicerate of 30 serives/hr. The dry-batch trucks you use forbringing concrete to the paver have an arrival rate of 7.5 arrivals/hr...
What is the overall specific gravity of a sample initially packaged with a moisture content of 3.5% below the optimum, then saturated (Assume that the soil sample can be compressed fully saturated with water without the occurrence of variation in ..
Two immiscible fluids are in contact. Fluid I is denser and is also well mixed. The concentration of species a is cao everywhere within this fluid and the temperature in fluid I is held constant at To.
