Water at a pressure of 13 atm, at street level, flows into a building at 3m/s through a 6 cm diameter pipe. The pipe tapers down to a 2 cm diameter by the top floor 50 m above. The density of water is 1,000 kg/m^3. Calculate the water pressure and velocity on the top floor?
A gas bubble is formed at the tip of a small tube which is completely immersed in a large body of liquid. The bubble remains in contact with the open end of the tube in a way that allows us to control the pressure P inside the bubble.
Compute points on the velocity profile from the pipe wall to the centerline of a 3/4-in Type K copper tube if the volume flow rate of water at 60 degrees F is .50 gal/min.
A 7 lb particle at rest is subjected to the action of its weight and forces F1= (2i+6j-2tk)lb, F2=(t^2i -4tj-1k) lb, and F3 =(-2ti) lb, where t is in seconds. the particle starts at the origin (0,0,0)
Starting from x = 0 with no initial velocity, the acceleration of a race car is defined by the relation a = 6.8e- 0.00057x , where a and x are expressed in m/s 2 and meters, respectively. Determine the position of the race car when v = 30 m/s.
A cylindrical metal specimen 12.0 mm in diameter and 120 mm long is to be subjected to a tensile stress of 40 MPa . at this stress level the resulting deformation is totally elastic.
A 900-mm strip of steel is bent into a full circle by two couples applied. Determine (a) the maximum thickness t of the strip if the allowable stress of the steel is 420 MPa, (b) the corresponding moment M of the couples.
Past experience indicates that the time for high school seniors to complete a standardized test is normal random variable with a mean of 35 minutes.
Determine the deflection angle to the last full station on a horizontal curve with Da=3 degrees. The PI is located at station 12.20 and the central angle is 24 degrees.
The current price of a company stock is $20.The company is a takeover target.If the takeover is successful.the company's stock price will increase to $30.If the takeover is unsuccessful.the stock price will drop to $12.
How much subsidence would be expected from an elastic confined aquifer that has a specific storage of 2.0*10^-6 (ft^-1), a decline in pressure of 200 (lbs/in^2), and aquifer thickness of 400 ft, and a porosity of 32 percent
How do you find the force ratio equation to determine the maximum total load that can be applied to a truss?
Calculate the total active earth force per foot of wall and its point of application from the base of the wall. Use Rankine theory. Calculate the total active earth force per foot of wall if the angle of wall friction between backfill and wall is 2..
