- 1. [15] Atmospheric pressure (P) decreases with increasing altitude (h) based on the following exponential function (with e as the base): P = Pº 1 exp Mgh RT where Pº=1 atm at h=0 (sea level) and T'is the average temperature of the atmosphere, M the molar mass of air (29 g mol-¹), and g the standard gravity. Please estimate the boiling point of water at atmospheric temperature T=293.2 K, and height h=3000 m. The heat of vaporization of water at 293.2 K is 44.22 kJ mol-arrow_forward(a) Is it true that 26.3 mpg gasoline translates to 319 g CO:/mi? i. Convert mpg (miles per gallon) to miles per kg (of gasoline) using the density of gasoline ii. Convert kg of gasoline to kg of C assuming the overall formula for gasoline is CıH1a5 ii. Convert kg of C to kg of CO2 iv. Now finally compute g CO:/mi corresponding to 26.3 mpg and compare to 319 g CO2/miarrow_forwardStock iron(II) solution (200Ug mL-1 Fe) ferrous ammonium sulfate hexahydrate mass= 0.1437g, transfer it to a 100 ml beaker. add 15 ml approx of water and 15m1 'approx of dilute sulphuric acid (2M H2SO.). then transfer FeII to 100 ml flask makeup to the mark with water. calculate the moles of ferrous ammonium sulfate hexahydrate solution in unit ug/mL.arrow_forward
- A core sample is saturated with an oil (?o = 35oAPI), gas and water. The initial weight of the sample is 224.14 g. After the gas is displaced by water (?w = 1 g/cm3 ), the weight is increased to 225.90 g. The sample is the placed in a Soxhlet distillation apparatus, and 4.4 cm3 water is extracted. After drying the core sample, the weight is now 209.75 g. The sample bulk volume, 95 cm3 is measured in a mercury pycnometer. Find the porosity, water saturation, oil saturation, gas saturation and lithology of the core sample.arrow_forward3.A core sample is saturated with an oil (po = 35°API), gas and water.

- Pentane (C5H12) is a liquid with a density of 0.626 g/mL near 25°C. Use the equation below to find the true mass of pentane when the mass weighed in air is 14.36 g. Assume that the air density is 0.0012 g/mL and the balance weight density is 8.0 g/mL. m=m'(1-(da/da))/(1-da/dw)arrow_forward2. In an ethanol production plant, a separator produces a 99% ethanol product from a feedstock stream containing 85% water and 15% ethanol at a rate of 450 Ib/min. The separator has two outlet streams: the ethanol product outlet stream (99% ethanol) and a residual water stream. 30% of the feedstock is bypassed and mixed with the residual water stream leaving the separator. If 60% of the ethanol entering the separator is recovered in the product stream, determine the composition of the residual water stream just after leaving the separator and the composition of the residual stream after mixing with the bypass stream.arrow_forwardTwo aqueous hydrogen bromide solutions containing 1.00 wt% HBr (SG=1.0041) and 60.0 wt% HBr (SG=1.6731) are mixed to form a 3.54 M HBr solution (SG=1.1935).

- Lactic acid is an important pharmaceutical product that is manufactured by fermentation of glucose. To separate the lactic acid from the biomass, filtration followed by centrifugation is employed. A mix containing 23% by mass lactic acid enters the filtration unit at the rate of 6,456 kg/hour. After filtration, the sludge of lactic acid/biomass contains 12 % by mass lactic acid and the filtrate itself contains 100% lactic acid by mass. The sludge then goes to the centrifuge where the solids generated contain 8% lactic acid by mass and the liquid portion stream has 100% lactic acid by mass. Calculate mass flow rate in kg/hour of the stream leaving the filtration unit containing pure lactic acid.
