b The number of liters of blood pumped through the lungs in one minute is given by C = where b is quantity of oxygen used by the body in one minute, a is the quantity of oxygen per liter of a-v blood that has just gone through the lungs, and v is the quantity of oxygen per liter of blood that is about to enter the lungs. Suppose a = 160, b=205, and v= 125. Estimate the change in C if a becomes 150, b becomes 200, and v changes to 125. Find the equation for the total differential of C to estimate the change in C. dC=da+db + dv
In a hybrid-engine vehicle, energy from battery (“b" in Amperes) and from 95 octane unleaded gasoline ("g" in liters) are used intermittently to maximize the distance to be travelled (mileage) between fill- ups and charge-ups.

While the rate at which ethanol can be produced is important, the total quantity of ethanol that can be produced from a given crop is also important. Use the information listed below to calculate the theoretical yield of ethanol from a 1 hectare plot of corn and a 1 hectare plot of sugarcane in the U.S. (1 hectare = 2 football fields). Show your calculations. Corn Yield: 138 bushels of seed per hectare 1 bushel seed = 2.8 gallons ethanol Sugarcane Yield: 89 tons sugarcane per hectare 1 ton sugarcane = 19.5 gallons ethanol
A swimming pool whose volume is 10,000 gal contains water that is 0.01% chlorine. Starting at t=0, city water containing 0.002% chlorine is pumped into the pool at a rate of 6 gal/min.
