Ex ....... HYDRAUE • The pump is to be connected to a rising main which has a diameter (D) of 400 mm and a length of 137 m.The entry exit and minor head losses in the pipeline can be taken as 80D in this particular situation. The friction loss can be approximated by h; = ALQ² / 1 2D5 with A=0.04. The static lift is 10 m. By considering a single pump (P). And two of the pumps in series (P+P) and parallel (P//P) determine: > the H-Q curve of the two pump combinations » Which combination will be capable of discharging at least 0.3 m³/s, with the ability to pump up to 0.35 m³/s if the need arises. %3D
An anaerobic digester (sealed, ID: 20 m) is used to produce renewable fuel from agricultural biomass. The head space pressure is maintained at 18.6 psi. A commercial steel pipe (20 cm) is connected to the bottom of the digester to remove the biofuel (y= 2000 N/m³, vapor pressure 0.2 psi) generated at 0.034 m³/s. A centrifugal pump (Taco® Model 4007, 7.00 in, operated at 1760 rpm) will be used. Assuming the head loss in the pipe is 225 ft, which of the following elevation can the pump be located?
