a new landfill has an ultimate fill capacity ie design volume of 55 x

Question

Fluid Mechanics

A new landfill has an ultimate fill capacity (i.e. design volume) of 5.5 x 107 ft³ for a population of150,000. The community's per capita generation rate is 5 lbm/day, the expected landfill load factor(LF) is 4.5 and the in-place compacted density is estimated to be 900 lbm/yd³.

Assume a 50% recycling rate and estimate landfill operating life in years

b) State one advantage and one disadvantage of methane generated by landfills

c) For large-scale MSW (municipal solid waste) management in the United States, brieflyexplain why landfilling is preferred over incineration

Fluid Mechanics

Water in the Belle Fourche Reservoir in Western South Dakotais transported to the water storage reservoir for the town of-Buffalo through a series of three pipes, all with friction factors of 0.02. The first pipe is 500 meters long with a diameter of 0.4meters; the second pipe is 600 meters long with a diameter of0.3 meters; and the third pipe is 500 meters long with a diameter of 0.2 meters. The water surface elevation of the Belle FourcheReservoir is 30 meters higher than the town's storage reservoir.Since the current piping is almost 60 years old, the town of Buffalo has decided to replace the piping system with a single pipe of constant diameter. You have been chosen to calculate the equivalent diameter for the single pipe design and determine the flow rate that will occur. Go to work.

Fluid Mechanics

A tank has a height of 800 mm and a length of 500 mm. The tank contains a liquid of RD 0.9.Determine:
a. The magnitude of the force on the side of the tank per meter width and its position relative to the base of the tank
b. The force on the base per meter width of tank.

Fluid Mechanics

A closed tank contains three different fluids with a vapor space above the oil, as shown in the figure below. Pressure gauge 1 reads the gauge pressure of the vapor space (P1) and pressure gauge 2 reads the pressure at the bottom of the tank (P2). When P1 = 25 kPa, determine:
a. Height of glycerine (h) in the tank if P2 = 95.66 kPa
. P2 reading if glycerine is replaced with water
