The two-tank system shown in Fig. P7-2 is operating at steady state. At time $t=0,10 \mathrm{ft}^3$ of water is quickly added to the first tank. Using appropriate figures and equations in the text, determine the maximum deviation in level (feet) in both tanks from the ultimate steady-state values and the time at which each maximum occurs. Data: $$ \begin{aligned} & A_1=A_2=10 \mathrm{ft}^2 \\ & R_1=0.1 \mathrm{ft} / \mathrm{cfm} \\ & R_2=0.35 \mathrm{ft} / \mathrm{cfm} \end{aligned} $$

A compact disc player rated as having speed of 8X will operate at an angular speed of about 4,000 rpm. a) What is the angular speed of the disc in the unit of radian/sec? b) By modelling the compact disc (CD) as a thin uniform disc with mass 10 g, an inner radius of 23 mm, and an outer radius of 58 mm, calculate the rotational inertia of the disc. c) If the torque provided by the motor rotate this disc has the magnitude of 0.1 N.m. What is the angular acceleration of the disk? d) For this angular acceleration, how many radians has the disc rotated, after 2 seconds? e) How many revolutions in (d) above?

1. Some of the butane, C 4 H10(g), in a 200.0 L cylinder at 25 . 0 ?C is withdrawn and burned at a constant pressure in an excess of air. As a result, the pressure of the gas in the cylinder falls from 2.53 atm to 1.10 atm. The liberated heat is used to raise the temperature of 152.5 L of water in a heater from 25.0 to 60 . 2 ?C. Assume that the combustion products are CO 2(g) and H 2O(l) exclusively, and determine the efficiency of the water heater. (That is, what percent of the heat of combustion was absorbed by the water?)
