Derive an expression for the speed of sound based on van der Waals' equation of state P= RT(v - b) -a/v2. Using this relation, determine the speed of sound in carbon dioxide at 50°C and 200 kPa, and compare your result to that obtained by assuming ideal-gas behavior. The van der Waals constants for carbon dioxide are a = 364.3 kPa · m6/kmol2 and b= 0.0427 m3/kmol.
The following wind conditions are expected: V = 10 i - 5 j mph for 0 10 hr. Draw to scale the expected streakline of the stream for t = 3, 10, and 15 hr.
The length of the pipeline in the building is 60 m, the water temperature is 20.C, and the water pressure on the top floor must be at least 150 kPa. Will a booster pump be required for the building If so, what power must be supplied by the pump
Measure the horizontal distance lengths of traverse legs using pacing, surveyor's tape and total station - familiarise with the use of GPS to measure coordinates and other computations (i.e. Slope and horizontal distances, area, perimeters etc.)
Photogrammetry Question:If you are given the parameters for a 2D affine transformation, DEMONSTRATE how you would determine which parameters are significant.
A pond has a surface area of 1.0 acre. A stream flows into the pond at 1.2 cubic feet per second for the entire year. The evaporation rate, also steady for the entire year, is 1 in. /month. Assume that the pond is in the shape of a cylinder.
Over a long period, total phosphorus (TP) has been discharged to a lake through sewage and surface water runoff at a rate of 10 tons/day. Measures were then taken to reduce the TP load to 1 ton/day. Assume that TP decays by a first order process with..
A concrete mix with a 3in slump, w/c ratio of .5, and sand with a fineness modulus of 2.4 contains 1700lb/yd3 of coarse aggregate. Compute the required weight of coarse aggregate per cubic yard.
A young engineer has invented holographic mobile phones and has approached a venture capital company to invest in it. The venture capital company considers the product to be an all or nothing product
Estimate the number of filters required and calculate the area of each filter (ft2), assuming that a length-to-width ratio (L:W) of 4:1 is employed in constructing the rapid sand filters and suing a filtration rate of 6 gpm/ft2.
A 3-ft diameter column with weight of 150 kg is placed on top of 1 m thick aggregate layer. The soil beneath the aggregate layer is sand. The friction angle of the aggregate is 36 degrees and the unit weight is 22 lb/ft3. What is the pressure acti..
