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.
