Suppose that 0.03% of plastic containers manufactured by a certain process have small holes that render them unfit for use. Let X represent the number of containers in a random sample on 10000 that have this defect. Find
a. P(X=3)b. P(X<=2)c. P(1<=X<4)
A fluid flowing in a pipe 30cm in diameter has a uniform velocity of 4m/s. The pressure at the center of the pipe is 40KPa, and the elevation of the pipe's centerline above an assumed datum is 4.5m. Compute the total energy per unit weight of the ..
Oil of a specific gravity of 0.75 is flowing through a 6-in pipe under a pressure of 15 psi. If the total energy relative to the datumplate is 8.0 ft below the center of the pipe is 58.6 ft, determine the flow rate of the oil.
A disabled automobile is pulled by means of two ropes as shown. The tension in AB is 400 lb and the angle is 20. knowing that the resultant of the resultant of the two forces applied at A is directed along the axis of the automobile, determine by ..
A discharge of 2,200 ft^3/sec flows in a trapezoidal channel at a normal depth of 8.0 ft. The channel has a slope of 0.01, a 12-ft bottom width, and side slopes of 1:1 (H:V). Determine the manning coefficient of channel roughness
An elbow, 90 degrees smooth bend flanged, is used in the Alaskan pipeline. Inside pipe diameter is 48 inches. Flow is 1.6 million barrels a day. 1 barrel=42 gal. Velocity is 8.27 ft/s. SG=0.93
A car is traveling toward a 20 degree slope at 60 mph. The wheels have a radius of 12 in, and the car's wheelbase is 100 in. What is the angular rotation rate of the car immediately after the front wheel contacts the slope
Calculate the volume of a cylinder that contains 60 lbm of carbon dioxide at 230°F and 23 psig pressure. Assume atmospheric pressure to be 14.7 psia.^4
The shape below has a cut along the entire length of the member thus making it an open section. The uniform thickness is 0.125in. Determine the maximum shear stress for the shape. Compare the stress for this open shape to a shape without a cut.
In a falling-head permeability test the initial head of 1.5m dropped to 0.5m in 4 h the diameter of the standpipe being 5mm. The soil specimen was 200mm long by 100mm in diameter.
Design a cord (design the constants k and ) so the cord stretches 2.5 times the unstretched length, and the acceleration of the jumper doesn't exceed 3g, and the cord has zero stiffness at the bottom of a 400ft drop.
The annual rainfall in basin follows a normal distribution with the mean value of 80 cm and standard deviation of 10 cm. What is the probability that annual rainfall exceeds 100 cm in any year
Q. What is the main objective of NASA's Mars Science Laboratory (MSL) mission? When was it launched and when and where is it scheduled to land on Mars? Explain the major differences between this mission and Mars Exploration Rovers (MER) mission?
