1.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.
2.Which process requires more energy: completely vaporizing 1 kg of saturated liquid water at 1 atm pressure or completely vaporizing 1 kg of saturated liquid water at 8 atm pressure?
3.For a .15 micrometer diameter spherical particle (density of particle = 2500 kg/cubic meter) determine the terminal settling velocity at standard conditions if the Cunningham correction factor is 2.11.
4.A 100 lb force vector F is aligned from A to B. Point A is located at the coordinates (2, 2, 2) and point B at (4,5,6). Calculate the moment of F about the y axis.
A minimum of how many satellites must be tracked in order to solve the positioning intersection equations dealing with position (ultimately northing, easting, and elevation coordinates)?
The tube is attached at B to a rigid plate that is itself attached at C to the bottom of an aluminum cylinder (E= 72 GPa) with a cross-sectional area of 250 mm^2.
Straight pipe, pump head=100 ft, pipe diameter=4inches, velocity is 10 ft/sec, no elevation changes. Water at 20C. What is the length of the smooth pipe
A pump of 80% efficiency lifts water from one large open tank to another; the difference in water surface elevations is 20 feet. The pipe is relatively smooth (f = 0.0122), and has 3 elbows, each with a loss coefficient of 2/3.
If the coefficient of sratic friction between the wheels at B and the ground is 0.5 determine if it is possible to pull at p=1200 lb without causing the wheels at B to slip or the front wheels of A to lift off the ground
A cable is made of two strands of different materials, A and B, and cross sections as follows: For material A, K = 60, 000 psi, n = 0.6, Ao = 0.6 in2 For material B, K = 30, 000 psi, n = 0.5, Ao = 0.3 in2
When the air temperature is 25°C, the pressure gage reads 210 kPa. If the volume of the tire is 0.025 m3, determine the pressure rise in the tire when the air temperature in the tire rises to 50°C.
A sample of 10 television tubes produced by a company showed a mean lifetime of 1200 hours and a standard deviation of 100 hours. Estimate
At the bottom of a loop in the vertical plane an airplane has a horizontal velocity of 315 mi/h and is speeding up at a rate of of 10ft/s^2. The radius of curvature of the loop is 1mi
