1.The partial pressure of the gasses in a 22,414-L volume of air at STP are: oxygen, 21,224 kPa; nitrogen, 79,119 kPa; argon, 0.946 kPa; and carbondioxide, 0.036 kPa. Determine the gram molecular weight of air.
2.Calculate the alkalinity as CaC03 of water that contains 85mg/l of HCO3, 120 mg/l of CO3 and 2 m/l of OH.
3.Select the lightest available W14 section to support the axial compression dead load of PD= 140 k and a live load of PL = 120 k if the length is equal to 14 ft and A992 steel is used. Assume that the top is unbraced (sidesway uninhibited), both ends are fixed, and there is no bracing along the length of the member.
A concrete mix with a 3-inch slump, w/c ratio of 0.50, and sand with a fineness modulus of 2.4 contains 1700 lb/yd^3 of coarse aggregate. Compute the required weight of coarse aggregate per cubic yard.
A student counted 92,90,92,91,93, and 91 paces in six trials of walking along a course of 200 ft known length on level ground. Then 85,86,86 and 84 paces were counted in walking four repititions of an unknown distance AB.
what is the difference between factor of safety in rankine & coulomb in overturning, sliding and bearing capasity ?
What are the basic differences between the AFL as a labor union and the CIO type of union?
Consider the rocket on a test stand . The nose of the rocket is fixed. The rocket is of length L, constant EA and constant m, mass per unit length. To investigate longitudinal dynamics, the rocket is modeled using axial elements of equal length.
Using the Gumbel probability function, estimate the probability that a maximum 24 hour depth in any year will exceed 160 mm. What is the probability that the maximum 24 hour depth will exceed 125 mm
A gas containing 80% CH4 and 20% (by mole) He is sent through a quartz diffusion tube to recover the He. 20% by weight of the original gas is recovered and its composition is 50% He.
how can Utah and other parts of the country have the same temperature but a different humidity?
A fireboat pump draws seawater (density=1.95 slugs/ft^3) from a 6 inch diamter submergred pipe that reaches 6 feet under the free surface and discharges 120 ft/s through a 2 inch diamter nozzle 10 feet above the free surface
A concrete pipeline is installed to deliver 6m^3/sec of water (10degressC) between two reservoirs 17 km apart. If the elevation difference between the two reservoirs is 12m, what is the required pipe size
Three completely mixed stabilization ponds are connected in series, and the system removes 99.998% from the total coliform count of the influent to the first pond. In stabilization ponds, coliform bacteria are removed by a first-order process
