Consider the two interconnected tanks shown in Figure 7.1.6.
Tank 1 initially contains 30 gal of water and 25 oz of salt, and
Tank 2 initially contains 20 gal of water and 15 oz of salt. Water
containing 1 oz/gal of salt flows into Tank 1 at a rate of 1.5
gal/min. The mixture flows from Tank 1 to Tank 2 at a rate of 3
gal/min. Water containing 3 oz/gal of salt also flows into Tank 2

The Bell and Gossett pump runs at the following conditions: Q = 1050 gal/min = 2.34 ft3/s and H = 105 ft, delivering water at 20ºC through a long, smooth, 8-in-diameter pipe. Neglect minor losses. How long is the pipe? For water at 20ºC, take ρ = 998 kg/m3 = 1.94 slug/ft3 and μ = 0.0010 kg/m·s = 2.09E-5 slug/ft·s. Take π = 22/7. Round the final answer to one decimal place. (in miles)

Consider two brine tanks. Tank Ti is filled with 30 gal pure water, and tank T2 with 10 gal water containing 4 lb salt. • Ti is filled with 3 gal/min water containing 3 lb/gal salt. • 11 gal/min well-mixed solution flows out of Tj into T2 • 8 gal/min well-mixed solution flows out of T2 into Ti. • Finally, 3 gal/min well-mixed solution is leaving T2. Let yi(t) be the amount of salt (in lb) in tank Ti after...

Use Laplace transforms to solve the problems in Exercise. A 500-gal tank contains 200 gal fresh water. A saltwater water solution enters the tank at a rate of 4 gal/min and the well-stirred solution leaves the tank at the same rate. Suppose for the first 10 min the salt concentration of the solution entering the tank is 1/2 Ib/gal and then the salt concentration of the entering solution is reduced to 1/4 Iblgal. How much salt is in the tank...
