A mining engineer plans to do hydraulic mining with a high-speedjet of water. a lake is located H=300 m above the mine site Waterwill be delivered through L=900 m of hte fire house with an inside diameter D= 75 mm and relative roughness E/D=0.01. couplings , eachwith a loss coefficient of k=0.15, are located every 10 m along thehose. the nozzle outlet diamter is d= 25 mm, its minor losscoefficient is k=0.02 based on outlet velocity. Estimate the maximum outlet velocity that this system coulddeliver.
A 2-inch diameter glass pipe is connected to a pipe network in which the pressure is 70 psig. If the length is 300 ft and the outlet is 10 ft above the pipe, determine the flow rate.
A simple supported beam 6m long is composed of two C200x28 channel RIVETED FRONT TO FRONT . What uniformly distributed load can be carried in addition to the weight of the beam w/o exceeding a flexural stress of 125MN/m^2
A finished 2 x 4 timber (actual size 1 5/8 in. x 3 1/2 in. x 10 ft long) is used as a fixed-end, fixed-end column. If the modulus of elasticity for the timber is 1600 ksi and a factor of safety of 3 with respect to failure by buckling is specified
given bulk density as 1300kg/cubic meter and field capacity as 22% by weight and permanent wilting point as 10% by weight calculate available water capacity.
Heat transfer through the walls and roof is estimated to be 5 40 kJ/hr per degree temperature difference between the inside and outside. a. If the outside temperature in the winter is - 5 C, what power required to drive the heat pum p (kJ/hr
A measurement was recorded as 171.278 m with a 30-m tape that was only 29.996 m under standard conditions. What is the corrected measurement?
The velocity of the center point of the wheel is constant at 20 ft/sec to the right. For the instant, determine the following: a) The velocity and acceleration of point B (which is attached to the wheel) measured with respect to ground.
Water flowing in a wide channel of depth 35 cm undergoes hydraulic jump that resulted in energy dissipation of 72%. Estimate (a) the downstream depth, (b) the volume flow rate per meter of width.
During the recent camping trip, a curious junior engineering student (like yourself) noticed that water is being discharged from a high reservoir to a stream in the valley through a 0.3 m diameter plastic pipe.
Determine suitable footing dimensions to suit the bearing capacity of 100kPa with a factor of safety 2.4
a 2000-mw electric generating station burns 278 tonnes of residual fuel oil per hour. the fuel contains 2.6 s and 1.2
The National Institute for Occupational Safety and Health (NIOSH) sets standards for CCl4 in air at 12.6 mg/m^3 of air (a time average over 40 hr). The CCl4 found in a sample is 4800 ppb. Does the sample meet the NIOSH standard
