Use the supplied software to track the process in Problem 3.96 in steps of 10?C until the two-phase region is reached, after that step with jumps of 5% in the quality. At each step write out T, x, and the heat transfer to reach that state from the initial state.
Problem 3.96
A cylinder fitted with a frictionless piston contains 2 kg of superheated refrigerant R-134a vapor at 350 kPa, 100?C. The cylinder is now cooled so that the R-134a remains at constant pressure until it reaches a quality of 75%. Calculate the heat transfer in the process.
When a channel of triangular cross section was new, a flowrate of Q caused the water to reach L = 2 m up the side of the channel. After considerable use
A particular crest vertical curve has long been criticized as being unsafe. Its length is 400 ft. The prevailing speed on the crest vertical curve is 50 mph. In its present condition, its tangent grades are +2% and -3%.
Three reservoirs are connected by three pipes with hA = 100 f t, hB = 20 f t, hC = 0 f t, l1 = 1000 f t, l2 = 500 f t, l3 = 400 f t and D1 = D2 = D3 = 1 f t. Determine flow rate into or out of each reservoir if friction in each pipe is 0.02.
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
A human with a surface area of 2 m^2 and a surface temperature of 27 degrees celcius radiates into a large room (which acts as a black body), the surfaces of which are at 15 degrees celcius.
The standard Proctor maximum dry unit weight of the sandy clay is 17.8 kN /m3 at an optimum water content of 10%. The specification requires 95% Proctor dry unit weight at acceptable water contents ranging from 9% to 10.8%. Is the specification me..
The speed limit for a highway is given as "V" in mph. The highway super elevation is given as "e" in ft/ft. The friction between tires and wet pavement is given as "f".
Estimate the concentration and the mass emission rate of NOx if a coal containing 1.5% nitrogen is combusted at 1400 k using an air/fuel ratio that is 1.5 times the stoichiometric ratio
(a) Determine the ratio of model flow velocity to prototype flow velocity over the spillway for dynamic similitude. (b) Determine the ratio of model discharge to prototype discharge for dynamic similitude.
A 100 mm nozzle is bolted (with 6 bolts) to the flange of a 300 mm horizontal pipeline and discharges water into the atmosphere. Calculate the tension load on each bolt when the pressure in the pipe is 600 kPa. Neglect vertical forces.v
The minimum teperature anticipated is 60 deg. F and the absolute viscosity (μ) is 2.359 x 10-5lb*s/ft2. Determine the diameter (ft) if two rapid-mixbasins are operating in parallel with a depth of 10 feet. Also calculate the power input to the bas..
