Resolving of Example (1-3) Two reservoirs with a difference in elevation of 15 m are connected by the three pipes in series. The pipes are 300 m long of diameter 30 cm, 150 m long of 20 cm diameter, and 200 m long of 25 cm diameter respectively. The friction factors for the three pipes are, respectively, 0.018, 0-020 and 0-019, and which account for friction and all losses. Further the contractions and expansions are sudden. Determine the flow rate in l/s. The loss co-efficient for sudden contraction from dia. 30 cm to 20 cm = 0.24. use the complex Liquid Piping system (series Piping

Water at 20°C is to be pumped from a reservoir (Z₁ = 5 m) to another reservoir at a higher elevation (zB = 13 m) through two 36-m-long pipes connected in parallel, as shown in Fig. 1. The pipes are made of commercial steel, and the diameters of the two pipes are 4 and 8 cm. Water is to be pumped by a 70 percent efficient motor-pump combination that draws 8 kW of electric power during operation. The minor losses and the head loss in pipes that connect the parallel pipes to the two reservoirs are considered to be negligible. Write a Matlab code to determine the 13 unknown quantities, namely i. ii. iii. iv. V. vi. vii. viii. the total flow rate (ỷ) between the reservoirs the volume flow rate (V₁ and V₂) through each of the parallel pipes. the velocities (V₁ and V2) through each of the parallel pipes. The total head loss, h₁ the head loss (hL,1 and h₁2) through each of the parallel pipes. Useful Pump head, hpump,u the Reynolds number (Re₁ and Rе2) through each of the parallel pipes. the…

The tank below is cylindrical and has a vertical axis. Its horizontal cross-sectional area is 10 m2. The tank has a layer of water under a layer of gasoline (S.G= 0.72). Three holes were drilled in the tank, one at the bottom of the tank, the second hole is in the water layer, 2 m from the bottom. The third hole was drilled 1S 11 in the gasoline layer 5 m from the bottom. The initial discharge velocities from the bottom and the third holes were also recorded as shown in the table below.

A circular thin plate is placed on the top of a tube, as  shown in the figure. (a) Find the exit velocity from the gap. (b) Find the velocity and pressure distributions in the gap between plate and tube’s tip for d/2 < r < D/2. Use ?air = 1.2 kg/m3 and Patm = 101,325 Pa
