. water at 20°C is to be pumped from reservoir 1 to 2 in a 6-in-diameter asphalted cast iron pipe at V = 6 ft/s. With 80 percent pump efficiency, the required power is 4.10 hp. What is he proper pipe length to match these conditions? Under the given flow condition, water properties are:p=1.94 slug/ft³ and u = 2.09E - 5 slug/ (ft s). For asphalted cast iron, e = 0.0004ft. 20 ft Pump

Water enters a perforated irrigation pipe (Length L, diameter D) with a uniform velocity Uin=10m/s. The water exits at the outlet with an average velocity Uout =8m/s and through N=10 perforations that all have the same diameter (d). The perforations are distributed at equidistant lengths, with the first one and last one located at a distance lo from the inlet and the outlet, respectively. It will be assumed that the average velocity through the perforations decreases linearly as one moves down the perforations. The flow rates through the different perforations have to be controlled to ensure proper irrigation of different plants. (a) Determine the diameters ratio (d/D) so that the average velocity at the first perforation id Vp1 Uin/5 and that at the last perforation is VpN = Vp1/10. (b) Generalize the previous analysis to obtain an expression of (d/D) in terms of a= Uout/ Uin, ß = Vp1/VpN, λ= Uin/Vp1, and N. (c) What is the ratio (d/D) that will ensure that all water exits through the…

A kitchen chimney, made of HINDWARE with exhaust pipe dia. of 90 cm supplies exhaust gas having flow rate of 1200 80 m3/hour. Length of exhaust pipe is 5m. Now BAJAJ Company wants to design a chimney to crater same flow rate but rectangular type with aspect ratio of 1.5. The length of exhaust pipes for both cases is assumed to be 5m. Also consider same friction factor for both the pipes as 0.182.Determine (i) the pressure drop for the HINDWARE duct. (ii) Considering the same pressure drop for the BAJAJ duct, determine its sides.
