Chapter 6, Problem 6.11P
Water at 20°C flows upward at 4 m/s in a 6-cm-diameter pipe. The pipe length between points 1 and 2 is 5 m, and point 2 is 3 m higher. A mercury manometer, connected between 1 and 2, has a reading h = 135 mm, with p1 higher. (a) What is the pressure change

A pipe inclined at 45° to the horizontal (Fig. 2) converges over a length l of 2 m from a diameterd1 of 200 mm to a diameter d2 of 100 mm at the upper end. Oil of relative density 0.9 flowsthrough the pipe at a mean velocity ?̅1 at the lower end of 2 m/s. Find the pressure differenceacross the 2 m length ignoring any loss of energy, and the difference in level that would beshown on a mercury manometer connected across this length. The relative density of mercury is 13.6 and the leads to the manometer arefilled with the oil.
For the system below, let the pump exhaust gasoline at 65 gallons per minute to the atmosphere through a 3-cm-dimater opening. When x = 3 m, y = 2.5 m and z = 2 m, the pipe friction head loss along the entire length of the pipe has been shown to be hf = 3.7 V 2 /(2g) empirically, where V is the velocity in the pipe. Estimate the horsepower to be delivered by the pump.
pls replyy
Gasoline (SG-0.7) flows down an inclined
pipe whose upper and lower sections are 90
mm (section 1) and 60 mm (section 2) in
diameter respectively. The pressure and
velocity in section 1 are 280 kPa and 2.3
m/s respectively. If the difference in
elevation between the 2 sections is 2.5m,
find the pressure at point 2.

- Assume an inviscid, incompressible flow. Also, standard sea level density and pressure are 1.23 kg/m3 (0.002377 slug/ft3) and 1.01 × 105 N/m2 (2116 lb/ft2), respectively. Consider a venturi with a small hole drilled in the side of the throat. Thishole is connected via a tube to a closed reservoir. The purpose of theventuri is to create a vacuum in the reservoir when the venturi is placed inan airstream. (The vacuum is defined as the pressure difference below theoutside ambient pressure.) The venturi has a throat-to-inlet area ratio of0.85. Calculate the maximum vacuum obtainable in the reservoir when theventuri is placed in an airstream of 90 m/s at standard sea level conditions.arrow_forwardNo wrong answer ..When 0.23 m³/s of water flows through a 300-mm diameter pipe, the level difference in a U-tube manometer, connected between two points, separated by 120 m, is 280 mm of mercury.
