A 10m height chimney has a 2.0m x 2.0m square cross section. The wind blows horizontally in a direction which is parallel to one of the diagonals of the cross section. Careful measurement shows that, at height y from the ground, the magnitude of the wind velocity is given by
u = 1.16 * Unom* log(750*y) for y > 1m
where Unom = 5m/s. The density and viscosity of air are 1.2 kg/m3 and 2.0x10-5m2/s respectively.
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.
The owner of a dive shop wants to purchase a constant displacement air compressor capable of simultaneously filling 10 SCUBA tanks. each having a volume of 0.4 ft^3. in 20 minutes.
A Class I rural highway segment of 10 miles in level terrain has a base free-flow speed (BFFS) of 65 mph. The cross section has 12-ft lanes and 6-ft clear shoulders on both sides of the road.
Phenol undergoes a first-order decay reaction in the CSTR with rate constant, k = 0.50 hr^-1. The current industrial pre-treatment permit for Phenol is 20 mg/l. The permit limitation may be changed, either higher or lower, in the future.
The initial conditions of the helium are 7 ft^3, 80 psia, and 100 F. The helium expands reversibly according to process PV^1.5=C until the pressure reaches 15 pisa.
The total dissolved inorganic carbon (TIC) of a sample of groundwater is 8.33 mM. The temperature of the aquifer is 15C, the pH is 7.5, and the ionic strength is 0.05 M. What is the H2CO3, HCO3-, CO3 2-, and the partial pressure of CO2? [Use activ..
At what depth will 400 cfs flow uniformly in an earth lined (n = 0.025) trapezoidal canal of base width 15 ft having side slopes 1 on 3 if the canal is laid on a slope of 1 in 10,000.
an air space above a long tube is pressurized to 50 kPa vacuum. water (20 degrees C) from a reservoir fills the tube to a height h. If the pressure in the air space is changed to 25kPa vacuum, will h increase or decrease and by how much
A proposed earthen dam will contain 5,000,000 cubic meters of earth. Soil to be taken from a borrow pit will be compacted to a void ratio of 0.78. The void ratio of soil in the borrow pit is 1.12. Estimate the volume of soil (cubic meters) that mu..
The dry weight of a core is 28.20 gm. When saturated with a brine having a density of 1.15 gm/cc, the weight increases to 31.50 gm. Calculate the apparent porosities if the matrix is 1) quartz or 2) calcite.
Water at a pressure of 13 atm, at street level, flows into a building at 3m/s through a 6 cm diameter pipe. The pipe tapers down to a 2 cm diameter by the top floor 50 m above.
Given the manometer reading at A is 100 kPa, D = 10 cm, d = 5 cm, VA = 2 m/s, and specific weight of water is 9800 N/m3, what is the manometer reading at B. Note that flow rate (Q) is constant and Q = VA
In polluted areas of Texas, registered vehicles must undergo an annual emissions inspection. In Fort Bend County (near Houston), 27 vehicles failed the emissions test, from among 200 randomly selected vehicles.
