2.1 Superposition. If there are two point sources released simultaneously, how do you obtain the concentration field as a function of space and time? You need to prove why your particular method can be applied. If one point source is at x = -L while the other is at x = L, what is the concentration at x = 0 (write the equation you would use to solve for C given D, M, A, and t)? Plot your result as a function of time with the values of D, M and A set as 1.0
The pressure in the steam condenser of a nuclear power plant is 1 psia. Calculate the absolute pressure head, the gage pressure, the gage pressure head, the vacuum pressure, and the vacuum pressure head under standard conditions.
The P.C. of a 3 degree curve, whose degree is based on a chord of100 ft. arc, is at Sta. 19+39.60 and the P.T is at Sta. 25+64.60. Calculate the deflection angle from the tangent at the P.C to each100-foot station on the curve and to the P.T.
A rigid rectangular shelf is suspended from a rigid ceiling by mean of four rods of diameter .505 inches. The two rods to the left L1 and L2, are made of steel
A smooth, vertical wall is 25 feet high and retains a cohesionless soil with a unit weight of 115 pcf and an angle of internal friction of 30 degrees. The top of the soil is level with the top of the wall, and the soil carries a uniformly
A manufacturing firm is considering two mutually exclusive projects. Both projects have an economic service life of one year, with no salvage value. The first cost of Project 1 is $1000 and the first cost of project 2 is $800. The Net year for each p..
A rectangular channel leading from an upstream lake has a bottom width of 20 ft, bottom slope of 0.0002, a Manning roughness factor of 0.016, a discharge of 403 cfs, and normal depth of 6.24 ft. Then at the downstream end the flow depth is 4.915 ft. ..
Soil falls from a conveyor belt into a cone shaped pile at a rate of 1000lb/min. The bulk density of the soil is 110lb/ft^3. The height of the pile is equal to the base diameter
Estimate the force on the chimney and the bending moment at the bottom of the chimney. You may assume that the effect of the wind on the first 1 m height of the chimney has a negligible effect on the force and the moment.
Assume that the interfacial tension between oil-water is 22 dynes/cm and the contact angle through water is 93
Determine the minimum size of the pad footing 2 metres wide for a steel column if a factor of safety of 2.0 is recommended (include an estimate of self weight of the footing in your calculations). The total load of the column is 447.644kN
An earth retaining structure is 12 feet high. The soil behind the earth retaining structure is a sand having a moist unit weight equal to 125 pcf, a saturated unit weight equal to 130 pcf, and a friction angle equal to 32 degrees.
Aluminum cans in the 1970's were considerably heavier than they arenow. For a 0.355-L (12 oz) aluminum can, with mass 0.0205 kg, andusing a 25 percent recycling rate, find the primary energy requiredto produce the aluminum in one such can.
