. What horsepower is supplied to air moving at 7m/min through a 70cmx90cm duct under a pressure of8cm of H2O?
Answer should be in psi.
Using velocity reduction method, design the duct system. Take the velocity of air in main duct as 8m/sec, air density 1.2kg/m. Coranch = 0.4 Coutlet = 1 2. Using equal pressure drop method, design the duct system. Take Ap = 1pa/m, air density 1.2kg \m. Cranch = 0.4 Coutlet = 1

- Problem 1 : A water tower holds a total volume of 100,000 L of water (10oC). The diameter of the tank is 6 m. The bottom of the tank (elevation 1030 m) connects to an outlet pipe (diameter 1/2 m) for supplying water to the water main (elevation 990 m). According to the local guidelines, pressure at any point along the water main must be between 30 and 60 psi (including the junction point with the outlet pipe). How will be water tower’s discharge rate (in gpm) be designed?arrow_forwardFind the loss in total pressure for each run in the simple duct system of Fig. 1, using the equal-friction method and in English unit. The total pressure available for the duct system is 0.12 in. wg (30 Pa), and the loss in total pressure for each diffuser at the specified flow rate is 0.02 in. wg (5 Pa). Duct fittings are listed in Table 1. Assume the duct dimeter in run 1 is 10 in. and the rest are 8 in.

- A home hot water heater contains 40 gal of water. Because of a failure of the heat control, heat is continuously applied to the water in the tank, increasing the temperature and pressure. Unfortunately, the relief valve is clogged and the pressure rises past the maximum pressure of the vessel. At 250 psig the tank ruptures. Estimate the quantity of water flashedarrow_forwardFor the system shown below, what is the compartment air pressure required to attain 1.2 litre of oil (specific gravity of 0.8) to flow through the 12 mm diameter pipe per a second?

- 5. A duct of 0.45 m diameter and 90 m long leads from a fan discharge chamber where the pressure is 15 mm of water to a plenum chamber where the pressure is 10 mm of water. In order to increase the flow, two alternatives are considered. One is to lay a duct of 0.3 m diameter and 90 m long in parallel with the duct of 0.45 m diameter. The other is to increase the diameter of 0.45 m diameter duct for the last 60 m length. Calculate the increased diameter so that this method gives the same flow as the 0.45 m and 0.3 m ducts in parallel. Assume that the pressures in the fan chamber and plenum chamber are unaffected by changes in the flow and consider duct friction losses only. The friction factor may be taken as 0.0o55. 6. A 0.3 m diameter circular duct carries standard air at a velocity of 360 m/min. It is replaced by a rectangular duct having the same pressure loss per unit length due to friction.
