A black oil reservoir has just been discovered. Reservoir pressure appears to be above the bubble-point pressure of the oil. Measured at reservoir conditions, 86.3 barrels per day enter the wellbore. The oil is processed through a separator into a stock tank. The stock tank accumulates 57.9 barrels of 44.20API oil each day. The separator produces 43,150 scf/d of 0.724 gravity gas, and the stock tank vents 7240 scf/d of 1.333 gravity gas. What is the formation volume factor of the oil? What is the solution gas-oil ratio? Which of the previous answers applies only at the bubble point?
An Industrial water shutoff valve is designed to operate with 40lbs of force and will encounter 150lbs of resistance force applied to a 2in diameter axle. What is the required actual mechanical advantage of the system?
Estimate the Schmid Factor, which is used to convert the CRSS into a critical tensile 'yield' stress. Use the measured angle between the slip trace and the sample long axis
Cracks propagate when the stress intensity factor exceeds a critical value and describe the fracture behaviour of the insulation tape loaded with a small crack.
What load P allow can be supported at the midpoint of the bar if the yield stress in the steel wires is 220 MPa and in the aluminium wire is 80 MPa? A saftey factor of n = 2 is needed.
Important information about Multipal choice question on mechanics, A machine is supplied energy at a rate of 4,000 W and does useful work at a rate of 3,760 W. What is the efficiency of the machine?
Determine the specified data for water at the states indicated and locate each state on a P-v and T-v diagram.
Find the needed length of the heated section of the tube and find the temperature of the water when it exits the heated section of the tube.
If the peak pressure and peak temperature of the cycle are 4.8 MPa and 2500, determine the net work done per cycle (kJ/kg) and the cycle thermal efficiency .
Cooling/Dehumidification of an air stream, A 1000 m3/minute air stream at atmospheric pressure is at a temperature of 82.2oC and a humidity of 60%. We want to cool the air + water vapor to 8.9oC to condense the water vapor.
You are designing a remote-area power supply based on a miniature wind turbine that is 20% efficient. Meteorological data indicates an average wind speed of 24 km/h at an air temperature of 10oC and pressure of 0.9 atm. The rotor has a diameter of..
your job is to create a design of Rankine cycle that create the most possible power from this heat source . you may use any working fluid for which you can find the properties , assume the turbines 92% efficient and pumps 85%
If the pipe is to be insulated with glass wool insulation (k=.05 W/m C) in order to decrease the temperature rise of water to .25 degrees C, determine the required thickness of the insulation.
