Do you agree that it is necessary to appraise design using a concept of value management? How can value management improve the efficiency of design consultants?
Find the absolute value of the magnitude of force vector B if the resultant force= 1000 lb, force vector A= 1000 lb, and the resultant forms a 45 degree angle with B, and vector B runs parallel to the y axis.
14-60E A centrifugal pump is used to pump water at 77°F from a reservoir whose surface is 20.0 ft above the centerline of the pump inlet. The piping system consists of 67.5 ft of PVC pipe with and ID of 1.2 in and negligible average inner roughness h..
Consider the pressure-driven flow between stationary parallel plates separated by distance 2b. Coordinate y is measured from the channel centerline. The velocity field is given by u=u max(1-(y/b)^2).
hree wells are drilled in an unconfined aquifer with the following coordinates and observed heads: Well 1: 0,200 (meters) 50 (meters) Well 2: 240,130 54 Well 3: 140, 320 63 (a) Find the magnitude and direction of the hydraulic gradient.
Using EES (or other) software and the relations given in Table A-33, generate the one dimensional normal shock functions by varying the upstream Mach number from 1 to 10 in increments of 0.5 for air with k =1.4.
Design a spreadsheet to estimate the dimensions of a tank for holding water. The spreadsheet should use input values from the user to return the height and diameter for a tank that will use the smallest amount of steel and therefore cost the least to..
Sled and rider with a total weight of 200 lb travel down smooth slope defined by equation y=x^2/20. At x=40 ft the sled's speed is 10 ft/s. At x=40 ft determine rate of increase of speed and the normal force which the slope exers on the sled. Neglect..
The station of a PI of a horizental curve is 60+20. The horizental curve has a degree of 4 and a length of 400ft. the othere given design perameters include. Superelevation runoff rate is 1/400. width of the pavement is is 15ft.
If the submarine operates at a depth of 75 meters (to the center of the side portals), what is the hydrostatic force on one of the side portals, in KPa?
Determine the moment about the origin O of the force F = 4i - 3j + 5k that acts at a point A. Assume that the position vector of A is (a) r = 3i - 6j + 5k, (b) r = i - 4j - 2k, (c) r = -8i + 6j -8k
A 780-g mass is attached to a vertical spring and lowered slowly until the mass rests at its equilibrium position 30 cm below the original length of the spring. It is then set into simple harmonic motion of amplitude 5 cm.
The surface energy of a single crystal depends on crystallographic orientation. Does this surface energy increase or decrease with an increase in planar density
