Two pipes of identical length and material are connected in parallel. The diameter of one is twice the diameter of the other. What is the ratio of the flow rates (Q2/Q1) in the two pipes
Differntial Leveling between BM's A,B,C,D, and A gives elevation differences (in meters) of -15.632, 32.458, 38.214, and -55.025, and distances in km of 4.0, 6.0, 5.0, and 3.0 respectively.
If an additional 11-ft lane is added (each direction) and all other factors stay the same, what will be the new level of service?
A ssume that one half of the energy incident on the collector goes to this reservoir, which, in turn, serves as a source for a heat engine. If the temperature of the atmosphere is 70 F,
Two parallel 40-N forces are applied to a lever. Determine the moment of the couple formed by the two forces (a) by resolving each force into horizontal and vertical components and adding the moments of the two resulting couples
A 4.00-cm-diameter, 0.80-m long rod of aluminum 7075-T6 is subjected to an axial tensile force with a factor of safety of 1.75. The yield stress and modulus of elasticity of aluminum 7075-T6 are 500. MPa and 210. GPa, respectively.
A small chunk of the original sample had a wet weight of 140.9 grams and weighed 85.2 grams after drying. Compute the water content, using the correct number of significant figures.
Assume the beam is 2" x 10" in cross section. Calculate the bending stress distribution that is present at the base of the cantilever and at every 2.5 ft increment toward the free end of the beam
When it is dried out in an oven, it weighs 122.7 g. The specific gravity of solids is found to be 2.66. Find the water content, void ratio, porosity, degree of saturation, and wet and dry unit weights.
Why is the ‘time value of money' important for the evaluation of engineering projects? Provide at least one practical example to support your view (max 2 pages).
You are going to assemble 1,000 bolt + hole combinations. The bolts have a mean diameter of 1.000 cm, normally distributed with standard deviation of 0.010 cm. The holes have a mean diameter of 1.030 cm, normally distributed with standard deviatio..
A discharge meter to be used in a 40 cm pipeline carrying oil (kinematic viscosity = 10-5 m2/s, density = 860 kg/m3) is to be calibrated by means of a model (1/4 scale) carrying water (T = 20°C and standard atmospheric pressure).
Find the dimensions of a rectangular concrete channel to carry a flow of 150 m3/s, with bottom slope 0.015, and mean velocity 10.2 m/s.
