A piston/cylinder has a water volume separated in VA = 0.2 m3 and VB = 0.3 m3 by a stiff membrane similar to the one in Fig. P6.128. The initial state in A is 1000 kPa, x = 0.75, and in B it is 1600 kPa and 250?C. Now the membrane ruptures and the water comes to a uniform state at 200?C with heat from a 250?C source. Find the work, the heat transfer, and the total entropy generation in the process.
a pipeline terminates in a nozzle of outlet diameter 0.15 m. the free jet from the nozzle is deflected through
Write out the final version of Hooke's Law which includes Young's Modulus. Draw the idealized Stress-Strain diagram for a material. On the drawing, please label: the yield stress, the plastic deformation, and the yield strain.
The maximum dry density determined in the laboratory for a quartz sand is 1800 kg/m^3. In the field, if the relative compaction is 90%, determine the hydraulic conductivity of the sand in the field compaction condition
Moist air at standard conditions is at a dry bulb temperature of 80 degree F and a relative humidity of 50%. It is cooled to 50 degree F. Use the psychromtric chart to determine:
Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall.
A pipe carrying oil of specific gravity (SG = 0.877) changes in size from 150 mm at section E to 450 mm at section R (E and R are arbitrary designations of the two points in the system). Section E is 3.66 m lower than R
Concept of CSTR, A lagoon is to be designed to accommodate an input flow of 0.10 m^3/s of nonconservative pollutant with concentration 30.0mg/L and reaction rate 0.20/day
Five years ago, GSI, an oil services company headquartered in Texas, issued $10 million worth of 12% 30-year bond with the dividend payable quarterly. The bonds have a call date of this year if GSI decides to take advantage of it.
Transportation need to evaluate the time spent in traveling from city A to city B. The distance between the two cities is a variable because the macro developed is to be used for other cities. 50% of travel time is done at a speed of 30 miles an
Design a helical compression spring to exert a force of 22.0 lb when compressed to a length of 1.75 in. When its length is 3.00 in, it must exert a force of 5.0 Ib. The spring will be cycled rapidly, with severe service required. Use ASTM A401 ste..
A completely mixed flow reactor, with a volume of V and a flow rate of Q, has a zero-order reaction, dA/dt = k, where A is the material being produced and k is the rate constant.
A 12.0 m rectangular channel, having a bed slope of 50 cm/km and a Manning roughness coefficient of 0.015, conveys water at a normal depth of 1.0 m. A dam is built across the channel at which the water depth is 2.0 m.
