Water is flowing through a horizontal pipe with an inside diameter of 8.00cm. The pipe narrows to an inside diameter of 3.75cm. Assume the water is an ideal incompressible fluid. What is the velocity of the fluid initially, v_1 (when It is flowing in the 8.00cm diameter section) if the velocity of the water in the narrow part of the pipe is measured at V_2 = 27m/s? If the initial pressure is known to be 670 kPa what is the...

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?

Determine the heat loss of seawater flowing through a 1 inch schedule 40 PVC pipe. The inner diameter of the pipe is 1 inch and the outer diameter is 1.049 inches. The temperature of the water is 50 degrees F and the outside air is 72 degrees F. The seawater is flowing at 3 GPM. The thermal conductivity of the PVC pipe is 0.20 [W/(mK)]. The heat transfer coefficient between the water and the pipe is 75 [W/m2K]. Take the same...

1. a) 1 m of water is flowing through a pipe in 10 minutes. The diameter of the pipe is 1.5 cm. Calculate the velocity of the water inside the pipe. 2. b) The pipe is extended to a bending and an elbow system. The head loss for bending and elbow system is 500 mm and 900 mm respectively. Calculate the loss coefficient for both the systems. Which one has higher loss coefficient and why?

Water flowing through a pipe suddenly comes to a section of pipe where the pipe diameter decreases to 86% of its previous value. If the speed of the water in the larger section of the pipe was 36 m/s, which is its speed in this smaller section?
Water is flowing through a 10-cm diameter water pipe at a rate of 0.2 m^3/s. Now...
Water is flowing through a 10-cm diameter water pipe at a rate
of 0.2 m^3/s. Now a diffuser with an outlet diameter of 20 cm is
bolted to the pipe in order to slow down water that exits into the
atmosphere, as shown. Disregarding frictional effects, determine
the force exerted on the flange due to the water flow. Density of
water = 1,000 kg/m^3.

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...

4. (25 pts) Water is flowing inside a thin wall, smooth pipe of diameter 0.05 m at a mass flowrate of 0.3 kg/s. The water enters the pipe at a mean temperature Tm,i= 80 °C and exits at Tm,o= 80 °C while the pipe surface temperature is maintained at Ts= 20 °C along its entire length. a. Is the flow turbulent or laminar? b. Calculate the average convection heat transfer coefficient inside the tube. c. Calculate the length of the...
