171 about industrial piping HOW IS THE HYDROSTATIC TEST PRESSURE DEFINED IN INDUSTRIAL PIPELINES?
In cold climates, water pipes may freeze and burst if proper precautions are not taken. In such an occurrence, the exposed part of a pipe on the ground ruptures, and water shoots up to 55 m. Estimate the gage pressure of water in the pipe. State your assumptions and discuss if the actual pressure is more or less than the value you predicted
Question 7 A liquid, with a density of 850 kg/m3 , is flowing downwards through a vertical pipe from a point a to a point B.The diameter at A is 150mm and the diameter at B is 75mm.Point B is 2.4m below point A.If 21 dm3 /s of the liquid flows through the pipe, the pressure gauges (connected at A and B) indicates a pressure difference of 12kPa.The loss of head across the pipe between A and B is given as KV2 /2g , where V is the velocity at A.Calculate the value of K.
When gage A indicates a pressure of 100 kPa gage, then cavitation just starts to occur in the venturi meter. If D = 40 cm and d = 10 cm, what is the water discharge in the system for this condition of incipient cavitation? The atmospheric pressure is 100 kPa gage, and the water temperature is 21°C. Neglect gravitational effects.

Suppose an aircraft is flying at standard sea-level at M = 0.8 and using a pitot-static tube for airspeed measurement. Determine the actual difference in total and static pressures as would be measured by the pitot-static system. Compare the speed of the aircraft as determined using the actual pressure difference and incompressible flow versus that knowing the actual Mach number. Use k = 1.4.
An airplane flies steadily at 200 mph at an elevation of 10,000 ft in a standard atmosphere as shown in the figure. Determine the pressure at the stagnation point on the nose of the airplane, point (2), and the pressure difference indicated by a Pitot static tube attached. Assume at a given altitude, pressure at point 1 is 1456 lb/ft^2 and air density is 0.001756 slug/ft^3.
At a certain flow range, for a system with certain geometric characteristics, in a pipe whose absolute roughness is 0mm, the pressure drop has a value of zero. True or False?
The pilot of a Boeing 767 determines that a total of 22,300 kilograms of jet fuel is needed to fly from Montreal to Edmonton. A floatstick check finds that there is 11,549 litres of fuel already in the tanks. How much fuel, expressed in litres, must be added to the tanks? The density of jet fuel varies with temperature. For the prevailing conditions take the density of the jet fuel to be 0.803 kg/L or equivalently 1.77 lb/L.
Given below are pipe lengths, sizes, and connections. All pipes have a friction factor of 0.020. If the flow from Ato B is 5 cfs. a) Determine the head loss in feet in PIPE 1 and PIPE 2 b) Determine the head loss in feet in PIPE 5 c) Determine the flow in the upper branch pipe Q2 in cubic feet per second d) Determine the total head loss in feet between the inlet A and the outlet D
A pump test for air flow is set up as shown below in which the pump draws air from the atmosphere into the 1-ft diameter pipe. The liquid in the differential manometer is water (? = 62.4 ?b/??^3) and the density of air is 0.00238 ?lug/??^3. Assume that the air flow is incompressible and frictionless. (a) Using the piezometer tube, compute the pressure in the pipe. (b) Using the Pitot tube and an energy equation, compute the velocity in the pipe. (c) Assuming that the air far away from the entrance to the pump is at rest (zero velocity), calculate the power delivered by the pump.
Chlorine gas is moving through a pipeline at a rate of 200 kilogram per hour while being pressured at 5 psig and operating at 800 F. If the pipe has a diameter of 5 inches, what is the flow velocity, expressed in meters/second?
