QUESTION 3 Water at a temperature of 60°C flows through a pipe of diameter 90 mm at a rate of 40 L/s. a) b) Determine the Reynolds number for this flow rate. What is the maximum flow rate at which laminar flow would be ensured?
1. For water at 20 C flowing through a straight smooth pipe at 0.06 m/h, the pipe diameter for which transition to turbulence will occur is approximately a. 1.0 cm b. 1.5 cm c.2.0 cm d. 2.5 cm e. 3.0 cm 2. Find the Reynold number, the roughness parameter, the friction factor f and the pressure drop for flow of water at 20 C through a 5 cm diameter pipe of roughness height E=0.5 mm if the flow rate is...
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 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 at 20°C flows in a steel pipe whose diameter is 26.65 mm. The volume flow rate of the water in the pipe is measured to be 3.155 x 10-4 3/s. The density at this temperature is given as 998.2 kg/m3. The mass flow rate is: m 0.315 kg/s | 1.22 kg/s O 0.522 kg/s O 0.575 kg/s 0.419 kg/s Previous Page Next Page Page 8 of 25
Water flowing through a 2.1-cm-diameter pipe can fill a 300 L bathtub in 4.4 min. What is the speed of the water in the pipe?
The water flowing through a 2.0 cm (inside diameter) pipe flows out through three 1.4 cm pipes. (a) If the flow rates in the three smaller pipes are 25, 19, and 12 L/min, what is the flow rate in the 2.0 cm pipe? (b) What is the ratio of the speed of water in the 2.0 cm pipe to that in the pipe carrying 25 L/min?
The water flowing through a 1.9 cm (inside diameter) pipe flows out through three 1.1 cm pipes. (a) If the flow rates in the three smaller pipes are 27, 16, and 12 L/min, what is the flow rate in the 1.9 cm pipe? (b) What is the ratio of the speed of water in the 1.9 cm pipe to that in the pipe carrying 27 L/min?
A vortex shedding flow meter is used to measure volume flowrate through a 100 mm diameter pipe. The pipe is housing a fluid of Reynolds number = 10000. If a bluff body of 50 mm inside the meter produces 20 vortices per second, calculate the volume flowrate through the pipe.
Water flowing through a 1.7-cm-diameter pipe can fill a 300 L bathtub in 5.9 min. What is the speed of the water in the pipe? Express your answer in meters per second.
