Water flows through a 200 m long ,30 cm diameter steel pipe with surface roughness 0.046 mm at a rate of 0.25 m^3/s .Find the pressure(P2)considering both friction and minor losses if P1=500 kPa;Z1=20m; Z2=10m ; L=200m ; K=10.0 ; D=30 cm?
The initial schedule called for 500 feet of pipeline to be installed each week, with the total construction cost projected to be $25 million. After 8 weeks, 4750' of pipeline has been installed at a cost of $11.25 million.
A solid composite shaft is subjected to a 2MN force. Section AB is red brass (E= 120 Gpa), and section BC is AISI 1010 steel (E=200GPa). Find the normal stress in each section and the total axil deformation of the shaft.
Indoor air quality is an under appreciated health hazardous. The air quality in a building can be modeled as a CSTR. Suppose that the carpet in a new office building releases formaldehyde at a rate of 10 micrograms per hour.
A steel tank hold 120 ft^3 of water at atmospheric pressure(14.7psi and 68.4 degrees f). the water is subjected to a 100 fold increase in pressure. determine the initial weight and final density of the water if the volume decreases by .545 ft ^3.
Determine the required pumping rate. the aquifer has T= 1600 m2/day and the wells each have radius of influence of 600m.
how kinematic and diffusion wave model been used for rainfall runoff modelling. main computer programme involved.
a tension member with cross-sectional area 3 in2 resists a load of 10 kips. How do you Calculate the normal and shear stress on planes making a 0, 20, 45, and 60 angle with the transverse section.
An early NASA/DOE wind turbine consisted of a 125.0-ft diameter, two-bladed horizontal axis rotor. Maximum power was achieved at a wind speed of 19.0 miles/hr.
A slurry containing 20 percent by weight of limestone (CaCO 3 ) is processes to separate pure dry limestone from water. If feed rate is 2000kg/h, how much CaCO 3 is produced per hour?
At a specified point on a highway, vehicles are known to arrive according to a poisson process. Vehicles are counted in 20 second intervals, and vehicle counts are taken in 120 of these time intervals.
An absorption column is to be designed to recover 99.5% of the NH3 from a feed stream, which is supplied at 72 F and an NH3 partial pressure of 10 mm Hg. The feed stream contains 2100 lbm/hr of air.
The volume flow rate of streams into the pipe is given by QA = 0.02t m 3 /s and that of stream B by QB = 0.008t 2 m 3 /s, where t is in seconds. The exit area of the pipe is 0.01m 2 . Find velocity and acceleration of the flow at exit at t = 1s.
