The flow through a ½ in diameter

Water is flowing without friction through a pipe. At the beginning of the pipe the water is flowing with a speed of 2.42 m/s, while at the end of the pipe the water is flowing at 5.74 m/s. The end of the pipe is higher than the beginning of the pipe. If the pressure is 60.8 kPa at the beginning of the pipe and 8.00 kPa at the end of the pipe, how much higher is the end of the pipe from the beginning of the pipe? [Answer in metres to 2 decimal places, but do not enter units with your answer] Your Answer: Your Answer

The Earth's atmosphere at sea level and under normal conditions has a pressure of 1.01x105 Pa, which is due to the weight of the air above the ground pushing down on it. How much force due to this pressure is exerted on the roof of a building whose dimensions are 10.2 m long and 14.5 m wide?

A tall graduated cylinder contains 7 cm of oil (density of 825 kg/m3kg/m3) on top of 20 cm of water (density of 1000 kg/m3kg/m3). The cylinder is open to the air. What is the pressure in the water, 3 cm above the bottom of the cylinder? (in Pa)  1.0323×105  1.0335×105  1.0353×105  1.0294×105  1.0157×105

A 1.00 m -diameter vat of liquid is 2.90 m deep. The pressure at the bottom of the vat is 1.50 atm. What is the mass of the liquid in the vat?

A 1.50 mL syringe has an inner diameter of 5.50 mm, a needle inner diameter of 0.230 mm, and a plunger pad diameter (where you place your finger) of 1.2 cm. A nurse uses the syringe to inject medicine into a patient whose blood pressure is 140/100. What is the minimum force the nurse needs to apply to the syringe? The nurse empties the syringe in 2.10 s. What is the flow speed of the medicine through the needle?

Blood plasma (at 37.0°C) is to be supplied to a patient at the rate of 2.80 × 10−6 m3/s. If the tube connecting the plasma to the patient’s vein has a radius of 2.00 mm and a length of 67.6 cm, what is the pressure difference between the plasma and the patient’s vein? Viscosity of blood plasma is 1.30 × 10−3 Pa·s. ____Pa

A fluid with density 1200 kg/m flows through this pipe. As the first location, A, the fluid travels at 7.5 m/s and at the second location, B, the fluid travels at 11 m/s. What is the difference in pressure between the two points? O-1.9 x 10 Pa +3.8 x 103 Pa -2.5 x 104 Pa -3.9 x 10 Pa O +5.0 x 104 Pa
