Consider a pipe that branches out into three parallel pipes and then rejoins at a junction downstream. All three pipes have the same diameters (D= 3 cm) and friction factors (f= 0.018). The lengths of pipe 1 and pipe 2 are 5 m and 8 m, respectively while the velocities of the fluid in pipe 2 and pipe 3 are 2 m/s and 4 m/s, respectively.

Solve for the headloss at the junction (m).

Expert Solution

In the solution, Since the pipes given are in parallel. Hence the head loss in each pipe up to junction point will be same.

All the parameters of pipe 2 were known and hence the head loss at junction is calculated by using the parameters of pipe 2.

And hence the unknown parameters for pipe 1 and pipe 3 are calculated by solving for head loss for the respective pipes.

Please give good ratings.

A pipe is manufactured according to a process that produces 1 defective pipe per 5000 pipes produced. All pipes produced are subject to an x-ray inspection. 99.9% of all defective pipes fail the inspection (are correctly identified as defective). 0.2% of good pipes fail the inspection (are incorrectly identified as defective). 1)What is the probability that a randomly-selected pipe will fail the inspection? (E.g. enter 50% as 0.50.) 2) What is the probability that a pipe that passes the inspection...

Two sewage pipes are mixed in a common sewer. The first pipe contains a strong acid, its pH is 3.00 and the flow rate is 50.0 L / s. The second conduct contains calcium hydroxide (a strong base) and its flow rate is 30.0 L / s. We want the common sewer to have a pH of 10.00. What is the molar concentration (in mol / L) of calcium hydroxide in the second pipe?

Two large tanks are connected by two pipes of different size in parallel. Water temperature is 20°C. The surface water elevation in the upstream reservoir (Reservoir I) is 175m. The length of each pipe is 1250 m, and other properties are specified in the following: Pipe A: diameter 0.5m, and frictional factor 0.025; Pipe B: diameter 0.25m, the frictional factor is not given, but relative roughness is 0.006 under the flow condition observed. Flow velocity in Pipe A is 2m/s....

A firm purchased copper pipes a few years ago at $10 per pipe and stored them, using them only as the need arises. The firm could sell its remaining pipes in the market at the current price of $9. What is the opportunity cost of each remaining pipe and what is the sunk cost? Assume that the fixed costs for a soybean farm, which include the costs of land, equipment and fertilizer is $10,000 per year and that labor is...
