EXAMPLE 5 In an oil refinery, a storage tank contains 2000 gal of gasoline that ini- tially has 100 lb of an additive dissolved in it. In preparation for winter weather, gasoline containing 2 lb of additive per gallon is pumped into the tank at a rate of 40 gal/min. The well-mixed solution is pumped out at a rate of 45 gal/min. How much of the additive is in the tank 20 min after the pumping process begins (Figure 16.7)? dy dt The differential equation modeling the mixture process is dy dt = 40 gal/min containing 2 lb/gal y(t) (40 x 2) - (45 x - (45 × V(C) v(t) = 80- - 45 gal/min containing lb/gal 45 y(t) 2000-5t/

Calculate the specific volume of a steam at 27.5 bar with a dryness fraction of 0.48 [Leave your answer to 4.decimal places) Answer:
The primary difference between these non-road (off road) types of diesel fuel is one contains a red dye and one does not. Otherwise the two diesel fuels are relatively identical. In some states there may be a higher level of sulfur in the off road diesel. From a regulatory perspective, the off road diesel tank is not regulated and is not required to have the leak detection, spill prevention or overfill prevention that a regulated tank is. Why is regular diesel fuel regulated (underground storage tanks) and off-road not regulated?
Problem 2: Entropy changes in free expansion and mixing. A. An isolated box has a partition dividing it into two equal parts, each with a volume V. Initially there are a total of N gas molecules all in the right-hand partition of the box. An opening is made on the partition. 1. What property (N, U, etc.) of the gas is changing as the gas expands into the left partition? V >. N. 2. Calculate, in terms of N and V only, the change in volumetric entropy ASvol Sf-S of the gas after it expands to fill both partitions. 3. Assume that each molecule has f degrees of freedom and that each begins with q energy blocks. What is the change in the energetic entropy, in terms of N and q? What is the total change in entropy of the gas? 4. Assume that the expanding gas is mol of CO2, each molecule with q = 12 energy blocks. Find the change in entropy of the gas, in J/K, after it expands. P.1
A diffusion process has reached equilibrium. This means that MARK ALL CORRECT ANSWERS the flow is equal in both directions. O the entropy has decreased. all flow has stopped. O the concentration gradient is zero.
