Water at 25˚C is flowing in a covered irrigation ditch below ground. Every 150 ft there is a vent 1.0 in. inside diameter and 1.0 ft long to the outside atmosphere at 30˚C. There are 15 vents in total. The outside air can be assumed to be dry. Calculate the total evaporation loss of water in lb/day.

Example 2 : Diffusion of Water Through Stagnant, Nondiffusing Air Water in the bottom of a narrow metal tube is held at a constant temperature of 20°C. The total pressure of air (assumed dry) is 1.0 atm and the temperature is 20°C. Water evaporates and diffuses through the air in the tube, and the diffusion path 22-Z is 0.5 ft long. Calculate the rate of evaporation at steady state in lb mol/hr.ft. The...

Be sure to answer all parts. On a humid day in New Orleans, the temperature is 23.0°C, and the partial pressure of water vapor in the air is 39.0 torr. The 9,000-ton air-conditioning system in the Louisiana Superdome maintains the inside air temperature at the same 23.0°C, but produces a partial pressure of water vapor of 10.0 torr. The volume of air in the dome is 2.4 x 106 m, and the total pressure inside and outside the dome are...

1. Water enters the constant 130-mm inside-diameter tubes of a boiler at 7 MPa and 65°C and leaves the tubes at 6 MPa and 450°C with a velocity of 80 m/s. Calculate the velocity of the water at the tube inlet and the inlet volume flow rate. [5-14] 2. Air enters a nozzle steadily at 50 psia, 140°F, and 150 ft/s and leaves at 14.7 psia and 900 ft/s. The heat loss from the nozzle is estimated to be 6.5...

(100 points) Water at 25°C is pumped at a rate of 0.075m's from a reservoir 20m above a pump to a free 1. discharge (this means discharged to atmosphere) 35m above the pump. The pressure on the intake side of the pump is 150kPa and the pressure on the discharge side of the pump is 450kPa. The pipe between the reservoir and the pump is 3 meters of Sin diameter cast iron. From the pump to the discharge the pipe...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
