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 insidediameter D= 75 mm and relative roughness E/D=0.01. couplings , each with 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 velocityestimate the maximum outlet velocity that this system could deliver.
a tape is calibrated and found to measure 100.04ft between the 0- and 100-ft marks. what measurements should be laid out to establish a horizontal distance of 682.25ft
A vehicle is traveling on a curved section of a road of radius 2500 feet at a speed of 60 mi/h. The motorist suddenly applies their brakes, causing the automobile to slow down at a constant rate. After 8 seconds the speed has been reduced to 45 mi..
if the velocity of the sled 10 sec from the start is 200mi\hr, determine the time average R of the total aerodynamic and mechanical resistance to motion. neglect the loss of mass due to exhausted fuel compared with the mass of the sled
design a bar screen for a peak average flow of 0.46m3/s.you can consider reasonable assumptions.
A concrete building has floor area 10 m by 20 m and is 4 m high. THe building has four windows with a height 1.6 m and a width 2 m. After 10 minutes gases in the room have an average temperature of 700 degree Celcius.
Two 9-in.-diameter pipes (pipe 1 and pipe 2) are supported every 7.5 ft by a small frame like that shown. Knowing that the combined weight of each pipe and its content is 30 lb/ft and assuming frictionless surfaces
Influent sample collected from a wastewater treatment plant was analyzed for various solids concentrations. Results indicated concentrations of Total Volatile Solids (TVS)
The allowable stress in a steel shaft with an outside diameter of 1.5in and an inside diameter of 1.1in is 12,000psi. What hp can the shaft deliver at 1750rpm
After the cone of depression has achieved equilibrium, the piezometric heads at two observation wells 40 and 95 m from the pumping well are measured as 78.9 and 83.4 above sea level, respectively.
