Write a computer program that generates a sequence of binomial random variables with parameters n=20 and p=0.3.
a) use the inverse c.d.f approach
b) use the property that the binomial random variable is the sum of n independent random variables each with parameter p.
Water enters a pipe at 100 psig and 70 degrees F. The density of water under these conditions is 62.3 lbm/ft^3. The pipe has an inside diameter of 4.5 inches. The mass flow rate of the water is measured to be 7500 lbm/hr.
Calculate the metric tons of gravel required to fill an excavated area 70 meters by 50 meters by 2 meters deep if the gravel has a density of 1890 kg/(m^3).
A vertical triangular orifice in the wall of a reservoir has a base 0.9m long,0.6m below its vertex and 1.2 m below the water surface. determine the theoretical discharge?
For Vectors A=(i + 2j - 3k) and B=(4i - 5j + 6k), determine:
What is the most significant difference between “free” jets and flows in confined structures (nozzles, pipes, etc.) in terms of formulation of force terms ÓF(i.e. left hand side) of the momentum equation? Assume all flows are subsonic and neglect the..
Ball A is thrown vertically upward from the top of a 30-m-high building with an initial velocity of 5 m/s. At the same instant another ball B is thrown upward from the ground with an initial velocity of 20 m/s. Determine the height from the ground..
The Record-a-Song company has contracted with a rising star to record eight songs. The sizes in MB of the different songs are 8, 3, 5, 5, 9, 6, 7, and 12, respectively. Record-a-Song uses two CDs for recording. Each CD has a capacity of 30 MB.
Consider a small simple Rankine Power cycle which produces 600kW power from an electric generator with an efficiency of 95%. The steam leaves the boiler at 1250psia as superheated steam and leaves the turbine at 2 psia with a quality of 90%.
Determine the percent error n in replacing the sine and the tangent of an angle by the value of the angle in radians for angle values 5 degrees, 10 degrees, and 20 degrees. Explain the qualitative difference between the sine and tangent results.
A hypothetical water treatment train consisting of coagulation/flocculation unit, filtration unit and chlorination system is used to treat surface water characterized by bacterial concentration of 800,000 CFU/L.
The US EPA has published the following data for the release to the Florida environment of sulfuric acid (H2SO4 ), the most widely used industrial chemical (in millions of pounds).
If the ball strikes the side of the building 2s after being thrown, at what height above the base of the building did the ball strike the building? What is the velocity of striking?
