The Lower Colorado River consists of a series of four reservoirs as shown in Fig. P12.8. Mass balances can be written for each reservoir and the following set of simultaneous
where the right-hand-side
(a) Use the matrix inverse to solve for the concentrations in each of the four lakes.
(b) How much must the loading to Lake Powell be reduced in order for the chloride concentration of Lake Havasu to be 75?
(c) Using the column-sum norm, compute the condition number and how many suspect digits would be generated by solving this system.

- 56.0 mL of two different liquids are poured through a funnel with a narrow exit tube, and the time for all of the liquid to flow through is recorded. Here are some results: time to flow through funnel trial Liquid X Liquid Y 1.60 s 3.62 s 1.52 s 3.44 s 1.44 s 3.56 s Note: the two liquids have the same density. Which statement below is true about these liquids based only on the data in the table? O The intermolecular forces in liquid X are stronger than those in liquid Y. The boiling point of liquid X is higher than the boiling point of liquid Y. The viscosity of liquid X is greater than the viscosity of liquid Y. The surface tension of liquid X is greater than the surface tension of liquid Y. The viscosity of liquid X is less than the viscosity of liquid Y. 3.arrow_forwardThe Simple Pendulum A H M Sketch a graph to show the predicted relationship. 2² H Task 8 In your group, discuss how to derive an equation to relate the initial pendulum height H to the bob's v 2 at its lowest point.

- You are working for a medical device start-up company as a design engineer. Your first task is to make measurements on the flow of blood plasma through your prototype. The device specifications require that 37°C plasma flow into the device pass through a bank of 100 tubes (0.2mm diameter), then exit the device. The total flow rate for the device must be 800 ml min^-1.
