2-) Given the following data:

Drilling Fluid Density : 12 ppg

Well Depth: 10,000 ft.

Drill Bit Nozzle Sizes: 13-13-13

Pump Horsepower: 1800

Pump Volumetric Efficiency: 80%

Maximum Pump Pressure: 4,500 psi

Minimum Flow Rate: 350 gpm

Parasitic pressure losses of 2,173 psi and 1,388 psi are anticipated while circulating mud at flow rates 500 gpm and 390 gpm respectively.

a-) Determine the parasitic pressure losses when the bit hydraulic horsepower is maximum.

b-) Determine the optimum flow rate when the bit hydraulic horsepower is maximum.

c-)Determine the pressure drop across bit nozzles when the bit hydraulic horsepower is maximum.

d-) Determine the optimum sizes of three nozzles to be used for the next bit run using the maximum bit hydraulic horsepower criteria.

A six-lane recreational freeway has the following characteristics: 12 ft lanes, 6 ft lateral clearances, 2 ramps/mi, 10% trucks (standard mix), peak-hour factor=0.95, level terrain, peak-hour demand=4,000 veh/h. Because the facility serves recreational users to a nearby ski area, the peak period occurs on weekends, and light to moderate snow is the normal weather pattern. If virtually all users of the facility are unfamiliar with the roadway, what is the expected LOS during the peak period?

Given two independent random samples with the following results: n1=18x‾1=141s1=13 n2=12x‾2=161s2=12 Use this data to find the 98% confidence interval for the true difference between the population means. Assume that the population variances are not equal and that the two populations are normally distributed. Step 2 of 3 : Find the margin of error to be used in constructing the confidence interval. Round your answer to six decimal places.
