Use the continuity of volume and mass flow for an incompressible fluid to determine the design characteristics of a gradually tapering pipe.
A pipe contains oil which has a density of 890kgm¯³. Its velocity is 12ms¯¹ at point 2 in the pipe.
Calculate the following:
The volume flow rate, the mass flow rate, and the flow velocities at points
1 and 3. See below for diameters.
The diameters of the pipe are:
(1) 100cm
(2) 70cm
(3) 290cm
The end of a large tubular work part is to be faced on a NC vertical boring mill. The part has an outside diameter of 38.0 in and an inside diameter of 24.0 in.
If the instrument and rod target heights were equal, calculate the difference in elevation from A to B.
Determine the energy loss due to the gradual enlargement from a 25 mm pipe to a 75 mm pipe when the velocity of flow is 3 m/s in the smaller pipe and the cone angle of enlargement is 20°C.
Two reservoirs are connected by a pipeline. The pipeline is 1 m in diameter and has a friction factor of 0.03. The elevation difference between the reservoirs is 30 m. The two reservoirs are 5 km apart.
If the max load is applied to the cylinder (6"x12") or (150x300mm) up to P=500 kips, what would be the compressive strength of concrete for (a) cylinder, (b) 150mm cube, and (c) 200mm cube.
How many 3?4-inch diameter rivets are required to transmit 55,000 lb from the two angles to the gusset plate if the allowable shear stress in the rivets is 15,000 psi? Assume each rivet carries the same amount of load.
A gas containing 80% CH4 and 20% (by mole) He is sent through a quartz diffusion tube to recover the He. 20% by weight of the original gas is recovered and its composition is 50% He.
A simple highway curve is planned to connect two horizontal tangents that intersect at sta. 2500 + 00.00 at an external angle of 52 degrees. For a design speed of 60 mi/hr and a curve radius of about 1.25 times the minimum allowable
