A car travels along a circular path such that its speed is increased by a_t=0.5e^t(m/s^2) ,where t is in seconds. The radius of curvature of the path is 30m.
Determine the magnitude of its velocity after the car has traveled s = 18m starting from rest. Neglect the size of the car.
Determine the magnitude of its acceleration after the car has traveled s = 18 starting from rest.
The vehicle was estimated to hit the light pole at 30 mph. The skid was 650 feet long. How fast was the car traveling before applying the brakes
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..
The rapid sand filter being designed for Laramie has the characteristics show below. Determine the head loss for the clean filter bed in a stratified condition. Depth = 0.75 m
Determine the diameter (in inches) and velocity (feet per second) of a concrete storm pipe required to carry a peak flowrate of 20 cfs at a slope of 1.0% Design the pipe to flow at 75% capacity and use a Mannings n of 0.013.
4 in diameter pipeline 200ft long discharges water from nozzle with 2 in diameter jet at an elevation which is 100ft below the water level of supply reservoir. find flow rate through pipe
The cost of a 100,000 bbl/d ethanol unit is $40,000,000. From historical records, the capacity exponent ratio for CCR is 0.75. Estimate the cost of a similar ethanol unit with a capacity of 135,000 bbl/d.
What is the percent change from 10m to the surface. Use absolute pressure and assume standard atmospheric conditions. Would the answer change with a different system of units.
if a ball is dropped from a height of 800 cemtimeters, and the impact velocity is 41 feet per second, determine the value of gravity in units of meters per second.
A biological reactor is used to treat wastewater from a small community (Q = 100,000 gpd). The influent BOD5 concentration to the reactor is 200 mg/L and the required effluent BOD5 concentration is 30 mg/L.
write computer code using Matlab that emoloyes the nelder and mead simplex method to solve the welded-beam design (benchmark problem
A dam project specifies 97% compaction. Lab tests on the soil being used indicate that it has a maximum dry density of 1900 kg/m3 at an optimum water content of 13.2%. Field tests give the following results: Field dry density is 1790 kg/m3 and 16...
Lab studies have shown that the rate constant associated with the process are as follows: k = 0.95 mg COD/mg VSS-day; Y = 0.48 mg VSS/ mg COD, half-saturation K = 85 mg COD/L; ke = 0.07 d-1.
