The width of the channel is reduced in the downstream. Upstream flow is subcritical. Please can you explain possible changes to the flow of the channel, and show how this would look on the specific energy diagram? Thanks for any help! Ive attached a picture of the specific energy diagram.
The shake-deflate baghouse on the power plant has 12 compartments, each with 100 bags (cylindrical) that are 0.2 meter in diameter and 7 meter long. Total gas flowrate is 300,000 m3/h which carries 60 g/m3 of particulate matter concentration. The pressure drop of a freshly cleaned baghouse is found to be 250 Pa, while the bags are operated until the pressure drop of 750 Pa. The cleaning frequency is twice per hour. The particle collection efficiency is 95%, and filter
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
Contaminant X is detected in a drink- ing water supply (4000 m³/day), and 94.99 percent of contaminant X must be re- moved to comply with federal water quality standards. If contaminant X has a "dimen- sionless" Henry's law constant, H, value of 0.25, then what is the design air-to-water flow ratio for an air stripping packed tower, assum- ing 3.5 times the minimum?
Estimate the total installed cost (in 1998 dollars) for an insulated, mild-steel reverse-air baghouse. The baghouse has 11 compartments with 8000 ft2 in each compartment, and has 8-inch glass fiber bags, with rings.
! Required information Oil flow in a journal bearing can be treated as parallel flow between two large isothermal plates with one plate moving at a constant velocity of 5 m/s and the other stationary. Consider such a flow with a uniform spacing of 0.5 mm between the plates. The temperatures of the upper and lower plates are 40°C and 15°C, respectively. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Vm/s u(y) The properties of oil at the average temperature of (40+15)/2 = 27.5°C are k = 0.145 W/m-K and μ = 0.605 kg/m-s = 0.605 N-s/m² By simplifying and solving the continuity, momentum, and energy equations, determine the maximum temperature and where it occurs. The maximum temperature is 337.32 °C. The location of the maximum temperature is 0.369 mm above the bottom plate.
Your client has request that you design a cloth media disc filter for the tertiary filter in a new plant. The flow is 3.2 million gallons per day (MGD). The Division of Drinking Water has approved the nordic CMF(5 gpm/sf). The manufacture indicates that the filter disc diameters are 2.4 m (8 ft). How many discs will you need assuming 1 disc will be out of service?
Use the design values for the coefficient C, from Table 8.3 unless stated otherwise. Use either of the various forms of the formula or the nomograph in Fig. 8.10 as assigned. 8.63 Water flows at a rate of 1.50 ft/s through 550 ft of 6-in cement-lined ductile iron pipe. Compute the energy loss.
For what velocity of flow of water in a new, clean 6-inch schedule 40 steel pipe would an energy loss of 20 feet of head occur over a length of 1,000 ft? Compute the volume flow rate at that velocity. Then refigure the velocity using the design value of Ch for steel pipe.
