- HEAT AND MASS TRANSFERarrow_forwardModelling Consider a liquid flow system consisting of a sealed tank with non-condensable gas above the liquid as shown in image.arrow_forwardModelling a) Develop a model for this system that can be used to find h1, h2, w2, and w3 as functions of time forany given variations in inputs.(b) Perform a degrees of freedom analysis. Identify all input and output Variables. The density of the incomingliquid, ρ, is constant.• The cross-sectional areas ofthe two tanks are A1 and A2.• w2 is positive for flow fromTank 1 to Tank 2.• The two valves are linear withresistances R2 and R3.arrow_forward
- Genetically modern humans appeared on Earth about 200,000 years ago, and biologically and behaviorally modern humans appeared about 70,000 years ago. The number of people and their effects on the planet were negligible, or as Douglas Adams says, "as near nothing as makes no odds," for most of the history of the planet. What year did the planet's population reach 1 billion people? 1200 1500 1650 1800 1950 Assume that the population has grown exponentially since that time. The approximate global population in 2012 was 7 billion people. What was the time interval (in years) required for the population to increase from 1 billion people to 2 billion people? 127 Your response differs from the correct answer by more than 10%. Double check your calculations. yearsarrow_forwardProvide stepsarrow_forwardExample A continuous fractionating column is to be design to separate 30 Ib/h of a mixture of 40 percent benzene and 60 percent toluene into an overhead product containing 97 percent benzene and a bottom product containing 98 percent toluene. These percentages are by weight. A reflux ratio of 3.5 mol to 1 mol of product is to be used. The molal latent heats of benzene and toluene are 7,360 and 7,960 cal/mol, respectively. Benzene and toluene form an ideal system with a relative volatility of about 2.5; the equilibrium curve is shown in Figure below. The feed has a boiling point of 95 °C at a pressure of 1 atm. (a) Calculate the moles of overhead product and bottom product per hour. (b) Determine the number of ideal plate and the position of the feed plate: (i) if the feed is liquid and at its boiling point. (ii)if the feed is liquid and at 20 °C (specific heat 0.44 cal/ g.°C) (iii) if the feed is a mixture of two-thirds vapor and one-third liquid. (c) If steam at 20 Ib/in? (1.36 atm)…arrow_forward
