A pressurized water tank has a gauge pressure (\(p_A\)) of 35 kPa. A 4-mm-diameter pipe that is 50 m long connects to another tank that is open to the atmosphere. The pipe has a roughness of 0.26 mm. Assume fully-developed flow for the entirety of the pipe. Neglect gravitational effects. Use properties of water at 20°C.Diagram Explanation:- The diagram shows a tank with a gauge pressure of 35 kPa connected to a second tank open to the atmosphere by a straight, horizontal pipe.- The pipe connects at the middle of the tank and is 50 meters long (denoted as \(L=50 \, \text{m}\)).- The pipe has a diameter of 4 mm (denoted as \(d=4 \, \text{mm}\)).- The roughness of the pipe is 0.26 mm.Questions:(a) Assuming the flow is laminar, what would the friction factor and Reynolds number be?(b) Assuming the flow is turbulent, what would the friction factor and Reynolds number be?(c) Is the flow laminar or turbulent? Which of the two Reynolds numbers calculated above is the true Reynolds number? Explain your reasoning in a few sentences.(d) What is the wall shear stress on the pipe?

EXAMPLE 5(H.W): One means of determining the surface level of oil in a tank is by discharging a small amount of air through a small tube, the end of which is submerged in the tank, and reading the pressure on the gauge that is tapped into the tube. Then the level of the oil surface in the tank can be calculated. If the pressure on the gauge is 30 KPa and the specific gravity of oil is S= 0.85, what is the depth d of oil in the %3D tank?
what will be the pressure gradient (kpa/m) at L=30 cm through the nozzle? At L=0, the liquid flows inside the nozzle has a specific gravity S=4.4, at L=0, the velocity is 2 m/s while at L=70 cm, the velocity is 6 m/s. Assume steady and inviscid flow. The velocity varies linearly with distance through the nozzle. 70 cm 6 m/s 2 m/s 60 cm Liquid

Q2. As a part of an Oil Company's Process Safety plan, crude oil tank fire scenario can be mitigated by pumping the tank empty in 1 hour. The crude oil is at a 9m level, with the tank diameter being 30m. It is planned pump the oil through a 200mm ID new commercial steel pipe (e = 0.046mm) to another tank 40m in diameter and 10m high. The pipeline runs to an equivalent length of 50m. a. In the time mentioned above, what minimum pump size (in HP) would be required to pump the tank empty. Assume pump efficiency of 80%. b. If a 100 HP (80% efficient) pump is available, how long will it take to empty the tank? c. What conclusions can be drawn about the viability of this approach? What kind of hazards can be foreseen in this operation from a process safety perspective? What can be a probable initiating cause of an accident? What can be a suggestion to mitigate the risks?
