1. Water flows in a 5-in-diameter pipe at 20?C with a mean flow velocity of 3 m/s. A sharp-edged orifice with a diameter of 2.5 in is to be used to measure the flow rate. What pressure differential would be indicated for a standard ASME installation? Express in units of Pa, in H2O, and psia.
2. An impact tube is used with an airflow at 10?C, 40 kPa, and a velocity of 700 m/s. What pressure will be indicated by the probe?
To apply shock loading to an artillery shell, a 20-kg pendulum A is released from a known hight and strikes impactor B at a known velocity Vo. inpactor B then strikes the 1-kg artillery shell C.
The owners wish to achieve an initial acceleration from rest of 22 ft/(sec^2) on a level paved surface. What is the minimum coefficient of road adhesion needed to achieve this acceleration
A power plant for a polar expedition uses ammonia and the boiler exit is 80?C, 1000 kPa, and the condenser operates at -15?C. A single open FWH operates at 400 kPa with an exit state of saturated liquid. Find the mass fraction extracted in the tur..
Prepare a set of suitable field notes for this project (see Plate B.6 in Appendix B) and compute the cut required at each stake. Close the level circuit on the benchmark.
The road is in good, dry conditions until 160 ft before the stalled car where it is wet and stays wet for the remaining length. What is the minimum distance from the stalled car at which the driver could apply the brakes and still stop before hitt..
The force on the piston is such that it maintains a constant pressure of 400 kPa inside. A valve is now opened nad steam at 1 MPa, 200 degrees C is allowed to enter the cylinder until the volume inside increases to 0.04 m^3.
An equal tangent vertical curve connects a -2% and a +3% grade. The low point of the curve is at elevation 297.88 ft. If the PVI is at elevation 295 ft, what is the design speed of the curve
