Water pressurized to an absolute pressure of 3x10^5Pa is flowing at 5.25 m/s in a horizontal pipe with radius r. Downstream, this pipe contracts to 1/2 of its cross-sectional area to a new section of the pipe with a radius r2=1 cm. Ignoring viscosity select the statements that are correct within 5% accuracy. There may be more than 1 correct answer.  A) the absolute pressure in the contracted pipe is 2.59x10^5 Pa. B) the speed of water flow in the contracted pipe is 2.63 m/s c) the water flow rate is 0.33m^3/s in the pipe with radius r. d)the water flow rat is 0.0033m^3/s in the pipe with a radius r2 e) the force required to pressurize the water in a pipe with radius r is 188.5 N.

Water is carried through a pipe. At point A, the diameter is 20 cm and the pressure is 130 kPa. At point B, which is 4.0 m higher than point A, the diameter is 30 cm. If the flow is 0.08 m^3/s, what is the pressure at the second point? 9.3 kPa Not any of the choices listed 93 Pa 0.92 atm 930 mmH20

On another planet that you are exploring, a large tank is open to the atmosphere and contains ethanol. A horizontal pipe of cross-sectional area 7.0×10−4m27.0×10−4m2 has one end inserted into the tank just above the bottom of the tank. The other end of the pipe is open to the atmosphere. The viscosity of the ethanol can be neglected. You measure the volume flow rate of the ethanol from the tank as a function of the depth hh of the ethanol in the tank. If you graph the volume flow rate squared as a function of hh, your data lie close to a straight line that has slope 2.09×10−5m5/s22.09×10−5m5/s2.   What is the value of gg, the acceleration of a free-falling object at the surface of the planet? Express your answer with the appropriate units.

A horizontal segment of pipe tapers from a cross-sectional area of 44.6 cm2 to 0.500 cm2. The pressure at the larger end of the pipe is 1.30 × 105 Pa, and the speed is 0.0400 m/s. What is the pressure at the narrow end of the segment? ___Pa

A brine solution with a density of 1230 kg/m³ moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is P₁ = 2.00 × 104 Pa, and the pipe diameter is 5.00 cm. At another point y = 0.40 m higher, the pressure is P₂ = 1.00 × 104 Pa and the pipe diameter is 2.50 cm. P₁ (a) Find the speed of flow (in m/s) in the lower section. m/s (b) Find the speed of flow (in m/s) in the upper section. m/s (c) Find the volume flow rate (in m³/s) through the pipe. m³/s

Water has a density of 1500 kg⋅⋅ m-3. One section of a horizontal pipe has a cross-sectional area that is 0.74 times another section. The gauge pressure at the smaller section is 18.5 ××104 Pa, and water flows through the section at a speed of  15.1 m⋅⋅s-1. Calculate the gauge pressure (in ×× 104 Pa) in the wider section of the pipe.
