A light oil is flowing through a commercial steel pipe of diameter D1. The head available to produce flow is independent of the flow rate. It is decided to utilise this head to increase the oil flow rate fourfold by installing a second pipe in parallel with the first pipe and of the same length. What should the diameter of the second pipe be, if: (i) flow in each of the two pipes is highly turbulent and the same roughness...

1-) In the pipe bundle lined up from steel pipes with outer diameters 1.8 cm, the number of rows of pipes perpendicular to the flow is 7 and the row spacing is St = 6 cm, the number of pipe rows in the flow direction is 7 and the row spacing is SL = 6 cm. In case the outer surface temperature of the pipes remains constant at 120 oC and water enters at 0.9 m / s velocity 46...

A horizontal pipe has an abrupt expansion from D1 = 5 cm to D2 = 10 cm. The water velocity in the smaller section is 8 m/s and the flow is turbulent. The pressure in the smaller section is F1 400 kPa. Taking the kinetic energy correction factor to be 1.06 at both the inlet and the outlet, determine the downstream pressure F2, and estimate the error that would have occurred if Bernoulli's equation had of water to be p...

Water is slowly drained from a large reservoir using two horizontal plastic pipes connected in series. The pipes are smooth and located at the bottom of the reservoir, as shown below. The first pipe has a diameter D1 = 10 cm and length L1 = 10 m, while the second pipe has a diameter D2 = 5 cm and a length L2 = 40 m (see schematic below). The water level in the reservoir is constant and equal to H...

4. Figure 2 shows two reservoirs which are connected by three pipes of different diameters. The length and diameter of each pipe are given in Table 1. The flow rate in the pipeline is 55 Ls. The entrance and exit from the pipes are sharp and the change between the pipelines in the cross sections is sudden. Assume the friction factor, /for the pipes as 0.01. (a) Analyse all the head losses which occur, giving an expression for each. (7...

Water (density = 1000 kg/m3, viscosity = 1.15 x 10-3 N-s/m2) is delivered from a large reservoir upstream (Section"1") through two mortar lined steel circular pipes arranged in series to another large reservoir downstream (Section "2") as shown in Figure E4.7 The upstream pipe is 80 m long and 0.15 m in diameter, whereas the downstream pipe is 50 m long and 0.1 m in diameter. Both pipes have sharp-edged entrance and exit. Consider both major and minor losses. Determine...
