: For the multiple pipe system below, calculate (a) the flow in each pipe and (b) Q2, the gauge pressure at point B. Two reservoirs are connected by a pipe 40 cm diameter and 2000 m long. Then, the pipe branches into two pipes each 30 cm diameter and 1000 m long. The friction factor coefficient in pipe 1 is 0.02 and in pipes 2 and 3 is 0.01. All the minor losses in the system can be neglected. The system geometry is such that the change in velocity head is negligible compared to the change in the head between any two points of interest, so the velocity heads can be ignored in an energy analysis. The reservoirs have h (m) difference in water levels. The value of h (m) can be found in Table 1 at the end of the questions.

A piston engine in which the bore and stroke are of equal dimension is referred to as a "square engine". An 8-cylinder square engine has a displacement of 305 in3. What is the bore and stroke? Round to the nearest thousandth of an inch. "bore" is the diameter of a cylinder, and "stroke" is the height of a cylinder (the distance the piston travels in one stroke). You will need the formula for the volume of a cylinder to solve this problem.

Question 1.1 a-c please explain solving method

this is 100% correct, but please tell me how to solve this carefully.
