Question

Water (density 1000 kg/m³) flows through a closed, frictionless pipe. At point A, the diameter of the pipe is
9.0 cm, the water's speed is 1.5 m/s, and the pressure in the pipe is 140 kPa. At point B, the pipe diameter
is still 9.0 cm, but the elevation of point B is 50 cm above that of point A.
What is the pressure at point B?
130 kPa
135 kPa
150 kPa
145 kPa
140 kPa

Given frictionless flow of water at 125.6 ft'/s in a long, horizontal, conical pipe of diameter 2ft at one end and 6ft at the other. The pressure head at the smaller end is 18ft of water. Find the velocities at two ends and the pressure head at the larger end.
A water barometer is used to measure air pressure in a duct where the air is being forced to ventilate a building. One end of the barometer is open to the atmosphere, and the other end is open to the inside of the ductwork. When the tube is bent in the shape of a U, the technician notes that the water level on the side toward the duct is lower than the side toward the atmosphere by 13.4 cm. What is the pressure difference in N/m2? The density of water is 1 gm/cm3 or 1000 kg/m3. Use 9.8 m/s2 for the acceleration of gravity.
Problem 3: Water flows through a horizontal cylindrical pipe from a smaller-diameter region to a larger-diameter region. At point A, where the pipe's diameter is 3.5 cm, the water's speed at 25.0 m/s. At point B, the pipe's diameter is 7.0 cm. (a) What is the water's speed at point B? (b) What is the pressure difference between points A and B? Which point has the greater pressure?
A level (horizontal) pipe contains a non-viscous, incompressible fluid with a density 1200 kg/m³ that is flowing steadily. At one position within the pipe, the pressure is 300 x 103 N/m2 and the speed of the flow is 20.0 m/s. At another position, the pressure is 200 x 103 N/m². What is the speed of the flow at this second position?
A horizontal pipe of cross-sectional area 0.29 m2 at height 6 m carries water at speed 1.9 m/s. The pipe turns upward and levels out again to horizontal at height 14 m, where the pipe narrows to 0.11 m. If the pressure is 202 kPa at the original height, what is the pressure in kPa at the final height? The density of water is 1000 kg/m3. kPa
