A manometer is used to measure the pressure difference between points A and B in a pipe. Water flows in the pipe, and the specific gravity of the manometer fluid is 2.8. The distances and manometer deflection are indicated. Find (a) the pressure differences PA - p8 , and (b) the difference in piezometric prcssure,pz,A - Pt.H· Express both answers in kPa.
A motorists inflates the tires of her car to a gauge pressure of 180 kilopascals on a day when the temperature is -8.0 degrees Celsius. When she arrives at her destination, the tire gauge pressure has increased to 245 kilopascals.
Estimate the size of a uniform, horizontal welded-steel pipe installed to carry 14.0 ft^3/sec of water 20 degreesC. The allowable pressure loss resulting from friction is 17ft/mi of pipe length.
A particular crest vertical curve (VC) on US 280 at Shelton Mill Rd has long been criticized as being unsafe. Its length is 400 feet. The prevailing speed on the crest VC is 50 mph. In its present condition, its tangent grades are G1=2 percent and..
A PVC pipe with a diameter of 30 inches will carry a flow of 20 cfs. the bottom slope is 0.005 and the roughness coefficient is 0.015. determine the normal depth, critical depth, velocity and the froude number.
Would a 30 slot stainless steel screen (2.0 m long; located at the bottom of the well) have sufficient collapse strength for this application?
A bar of monel metal (length L=9 in., diameter d=0.225 in.) is loaded axially by a tensile force P. If the bar elongates by 0.0195 in., what is the decrease in diameter d What is the magnitude of the load P
How far apart must two 18 , diameter tanks be placed such that their stress overlap is not greaer than 10% of the contact stress at depths of 10, 20, and 30 m
Knowing that the coefficient of kinetic friction between a sled and the run is 0.10 and that the speed of the sled is 25 ft/s at B, determine the tangential component of the acceleration of the sled a) just before it reaches B, b) just after it pa..
The casting has a mass of 3 Mg. Suspended in a vertical position and initially at rest, it is given an upward speed of V mm/s in 0.3s using a crane hook H. Determine the tension in cables AC and AB during this time interval if the acceleration is ..
The slope distance between two points is 72.665 m, and the difference in elevation between the points is 1.120 m. Compute the horizontal distance.
A multiple-piston hydraulic jack has two output pistons, each with an area of 250 cm^2. The input piston, whose area is 25 cm^2, is concerned to a lever that has a mechanical advantage of 9:1.
A car traveling over a hill at constant speed starts to lose contact with the ground at O. If the radius of curvature of the hill is 85 m, determine the speed of the car at O.
