Describe the operation of a piping system, actual or hypothetical, of industrial sewage and drainage, by means of a flowchart. The system must contain two branches with diameters different from the diameter of the main branch. Indicate in this system the equipment that supplies energy (reservoirs, pumps, boilers, tanks, compressors, etc.). Indicate in this system the energy-consuming equipment (vessels, heat exchangers, machines, processes, etc.). Indicate the proper locations to install relief valves, flow valves, traps, drains, and vents. Define the basic operating conditions (temperature, maximum and minimum operating pressures, fluid type). Define the basic physical conditions (material specification, pipe diameter) Define the maximum design pressure, to be considered the MAOP.

Hydrogen (v = 1.08 E-4 m²/s) flows at 0.9 L/s through a 100-mm-diameter pipe. Describe the %3D type of flow.

As the project engineer for your consulting firm, you are in charge of designing a flocculation tank to treat municipal drinking water. The design flow for the plant is 0.050 m3/s. The average water temperature is 10oC. The following design assumptions for the flocculation basin have been made:Number of tanks = 1Number of compartments in tank: 3Tapered G in 3 compartments: 60, 50, and 20 s-1Detention time = 30 min for entire flocculation basinDepth = 3 mTanks will have a square compartment plan (overhead) view1 Horizontal shaft paddle wheel per axis will be usedPaddle wheels will have 4 arms and 2 blades/armPaddle blades are 3 m long by 0.6 m wide. Assume blade spacing (diameter) of 1 and 2 m. Design the flocculation tank by providing the following for the first two compartments only:a) Tank and compartment dimensions in mb) Water power input in kWc) Rotational speed of the paddle wheel shaft in rpm

If the velocity of water is 8m/s and the pressure is 140kPa on the discharge side of a pump. How much power (in horsepower) is required to drive it if the diameter of the suction side is 600mm? If the pump is rated at 190hp, what is the efficiency of the pump neglecting energy losses in the system? Use diameter of pipe on discharge side equal to 50cm and the pressure on the suction side of the pump is 90kPa.

The system presented on Figure 1 pumps water from the left reservoir to ensure a water in the elevated basin stays level. Knowing that the offset from water-surface to water-surface 7.5m and the water temperature is 5oC, you must: a) Determine the out-flow from the basin's orifice; b) Determine the efficiency of the pump (n) feeding the basin if the pump's absorbed power is 2550W; Consider that hs=0 c) Determine how long it will take for the basin to fully empty if the pump ceases to function.

Design the chilled water pipe system shown in the figure and calculate the power of the pump. Take the pressure loss in each elbow as 250 Pa. * 50 Lit/min 30 Lit/min 40 Lit/min

2. A water discharge 8 m³/s is to flow through this horizontal pipe, which is 1 m in diameter. If the head loss is given as 7 (V is velocity in the pipe), how much 2g power will have to be supplied to the flow by the pump to produce this discharge? Plot also the EGL and HGL against the given diagram. |Elevation = 40 m Pump Water 1 m - Elevation = 20 m - Elevation = 10 m 300 m- 300 m
