Gasoline is being discharged from a pipe at point 2 at elevation 66.66 m. Pint 1, located 965.5 m along the pipe from point 2, is at elevation 82.65 m, and the pressure there is 2.50 kPa. If the pipe roughness is 0.500 mm, what pipe diameter is needed to discharge gasoline ( γ= 7.05 kN/m3, μ = 2.92x10-4Ns/m2, ρ = 719 kg/m3) at a rate of 0.10 m3/s? Solve this problem using two different approaches.
1) Use Moody chart and manual iteration (Answer: Q = 0.1394 ft3/s),
2) Use Colebrook equation and any kind of software tool such as Mathcad, excel or a programmable calculator.
The cross sectional dimensions of a 4-ft-long wood member at 30% moisture content is 1.5 in. x 7.5 in., and its weight is 11 lb. At oven-dry condition, its dimensions and weight are 1.35 in x 6.8 in., and 10.2, respectively. What is its specific g..
A diffuser receives an ideal gas flow at 100 kPa, 300 K with a velocity of 250 m/s and the exit velocity is 25 m/s. Determine the exit temperature if the gas is argon, helium or nitrogen.

The beam is loaded with a concentrated live load of 10 kips at the center of its span, in addition to its own weight.. The dead load includes the beam weight. The steel is A242, Grade 50.
A tank is divided into two equal chambers by an internal diaphragm. One chamber containes methane at a pressure of 500 bar and a temperature of 20 C, and the other chamber is evacuated.
water flows from a lake as is shown in fig. p8.40 at a rate of 4.0 cfs. is the device inside the building a pump or a turbine? Explain and determine the horsepower of the device. neglect all minor losses and assume the friction factor is .025
A nuclear power plant produces heat through fission of uranium which is used to create high pressure steam. The steam expands through a turbine to a low pressure in order to produce work which drives a generator to produce electric power.
The grade elevation at station 25+00 is to be 946.52 ft. What will be the grade elevation at station 34+86.20 if the grade linerises at the rate of 1.785% between these two points?
After drying in the oven, it weighs 4.44 kg. The relative density of the grains is 2.70. Determine the degree of saturation, void ratio, porosity and moisture content of the soil in its natural state.
Two level sections of an east-west highway (G=0) are to be connected. Currently, the two sections of highway are separated by a 4000-ft (horizontal distance), 2% grade. The western most section of highway is the higher of the two and is at elevati..
