Using continuity equation,
A1 v1 = A2 v2
Velocity, v1 = Q/(pi r1^2)
v1 = 7500/(pi x 3.85^2) = 1.61 m/s
v2 = 7500/(pi x 2.15^2) = 5.16 m/s
Using Bernoulli's theorem,
P2 = P1 + 0.5 p (v1^2 - v2^2)
P2 = (2.45 x 10^5) + 0.5 x 1000 (1.61^2 - 5.16^2)
P2 = 2.33 x 10^5 Pa

A golf course sprinkler system discharges water from a horizontal pipe at the rate of 7500 cm3/s . At one point in the pipe, where the radius is 4.05 cm , the water's absolute pressure is 2.25×105 Pa . At a second point in the pipe, the water passes through a constriction where the radius is 2.20 cm . What is the water's absolute pressure as it flows through this constriction? P= ___________Pa
A golf course sprinkler system discharges water from a horizontal pipe at the rate of 7100 cm3/s . At one point in the pipe, where the radius is 4.20 cm , the water's absolute pressure is 2.45×105 Pa . At a second point in the pipe, the water passes through a constriction where the radius is 1.75 cm . What is the water's absolute pressure as it flows through this constriction? (in Pa)
A golf course sprinkler system discharges water from a horizontal pipe at the rate of 7250 cm3/s . At one point in the pipe, where the radius is 3.90 cm , the water's absolute pressure is 2.25×105 Pa. At a second point in the pipe, the water passes through a constriction where the radius is 2.05 cm . What is the water's absolute pressure as it flows through this constriction? P = Pa
Water flows at a rate of 21 L/min through a horizontal 8.0-cm-diameter pipe under a pressure of 3.8 Pa . At one point, calcium deposits reduce the cross-sectional area of the pipe to 39 cm2 . What is the pressure at this point? (Consider the water to be an ideal fluid.) Express your answer using two significant figures. p= Pa
Water flows at a rate of 22 L/min through a horizontal 7.0-cm-diameter pipe under a pressure of 17.0 Pa . At one point, calcium deposits reduce the cross-sectional area of the pipe to 21 cm2 . What is the pressure at this point? (Consider the water to be an ideal fluid.) Express your answer using two significant figures.
Water flows through a pipe as shown in the figure. The pressure at points 1 and 2 respectively is 1.80 x 105 Pa and 1.20 x 105 Pa. The radius of the pipe at points 1 and 2 respectively is 3.50 cm and 1.20 cm. If the vertical distance between points 1 and 2 is 2.75 m, determine the following. (a) speed of flow at point 1 m/s (b) speed of flow at point 2 cm/s (c) volume flow rate...

Problem 1 (30): Water (density p 999 kg/m') flows through a pipe bend and constriction as shown in the schematic. The pipe section is connected to input and output pipes at loc ations A and B. the inlet point A is located 1 m higher in elevation compared to the exit point B. The total loss d ue to pipe friction, bend, and constriction can be approximated as EU = etY2 with et = 2.1 2 Find the total force...
Water flowing out of a horizontal pipe emerges through a nozzle. The radius of the pipe is 1.7 cm, and the radius of the nozzle is 0.49 cm. The speed of the water in the pipe is 0.78 m/s. Treat the water as an ideal fluid, and determine the absolute pressure of the water in the pipe. Pa
10. Water flows at a rate of 610.0 liters/min through a horizontal 5.10-cm diameter pipe under a pressure of 6.20x10^5 Pa. At one point, calcium deposits reduce the cross-sectional area of the pipe to 5.50 cm². What is the pressure at this point?
