Explanation Given data: Flow rate of the pump ( Q ) is 36.0 gal / min . Velocity of the water in the pipe ( v ) is 10.0 ft / min . Formula used: Write the expression for flow rate of the water through the pipe as follows. Q = v A (1) Here, v is the velocity of the water flow, and A is the area of the pipe. Write the expression for area of the pipe as follows. A = π 4 d 2 (2) Here, d is the diameter of the pipe. Calculation of diameter of the pipe ( d ) : From equation (2), substitute ( π 4 d 2 ) for A in equation (1). Q = v ( π 4 d 2 ) Rearrange the expression to find the diameter of the pipe as follows. d = 4 Q π v Substitute 36.0 gal / min for Q , and 10.0 ft / min for v to obtain the diameter of the pipe as follows. d = ( 4 ) ( 36.0 gal / min ) ( π ) ( 10

Four capacitors are connected as shown in the figure below. (Let C = 12.0 µF.) A circuit consists of four capacitors. It begins at point a before the wire splits in two directions. On the upper split, there is a capacitor C followed by a 3.00 µF capacitor. On the lower split, there is a 6.00 µF capacitor. The two splits reconnect and are followed by a 20.0 µF capacitor, which is then followed by point b.
