What depth (in feet) of oil with a specific gravity of 0.87, will produce a pressure of 40.0 psi? What depth of water?

Two materials, A and B, are to be separated using two unit operations, 1 and 2. The feed has 10 tons/h A and 4 tons/h B. The split (fraction of material rejected by each operation) is given in Table P5-14. a. Which sequence of operations, (l?2) or (2?1), will yield the greatest recovery of material A? b. What will be the purity of material A using that sequence? c. What will be the efficiency of separation for the entire process train with regard to material A using the Worrell-Stesed equation?

A jet plane taking off creates a noise with a magnitude of approximately 125 dB. What is the magnitude of the pressure disturbance (in Pa)?

According to Figure 5-20, is ii possible to completely separate one of the four materials from the other three? Explain your answer.

Refer to Figure 7.24. The following data were collected during the field permeability measurement of a confined aquifer using a pumping test. Determine the hydraulic conductivity of the permeable layer. Use Eq. (7.49). Thickness of the aquifer, H = 4.5 m Piezometric level and radial distance of the first observation well: h1 = 2.9 m; r1 = 17.8 m Piezometric level and radial distance of the second observation well: h2 = 1.8 m; r2 = 8.1 m Rate of discharge from pumping, q = 0.5 m3/min

For the fin equation described in Problem 6.25, if the units of T, h, P, A, and x are expressed in degree Rankine (R), Btu/hr ft2R, ft, ft2, and ft, respectively, what is the appropriate unit for thermal conductivity k if the fin equation is to be homogeneous in units? Show all steps of your work.
