the auditor should ensure control testing is performed for periods both before and after the accounting change became effective.

A major change in the accounting system has taken place during the year. The effect on control testing is that:

a. the auditor should ensure control testing is performed for periods both before and after the accounting change became effective. b. the auditor can assume the accounting system change was necessary and has improved the client’s controls, so should only test the period following the change. c. the auditor can assume the accounting system change was necessary and has improved the client’s controls, so should only test the period before the change. d. the auditor will not conduct control testing because the client has clearly thought about making sure the accounting system works well.

erive the differential equations in terms of the liquid heights h1 and h2.

  Figure 7.18 shows a liquid-level system in which two tanks have cross-sectional areas A1 and A2, respectively. The volume flow rate into tank 1 is qi. A pump is connected to the bottom….

Derive the differential equation relating the liquid height h and the volume flow rate qi at the inlet.

  Consider the single-tank liquid-level system shown in Figure 7.19, where the volume flow rate into the tank through a pipe is qi. The liquid leaves the tank through an orifice….

Derive the differential equations in terms of the liquid heights h1 and h2.

Figure 7.20 shows a hydraulic system of two interconnected tanks that have the same cross-sectional area of A. A pump is connected to tank 1. Assume that the relationship between the….
