A control group is a group separated from the rest of the experiment such that the independent variable being tested cannot influence the results. While all experiments have an experimental group, not all experiments require a control group. […]
How do we determine the total discharge through parallel pipes?
How do we determine the total discharge through parallel pipes? Explanation: Total discharge in parallel pipes are determined by adding the discharges so developed in individual pipes. If Q1 is the discharge through pipe 1 and Q2 is the discharge through pipe 2. Then the total discharge through parallel pipes is equal to Q1+Q2. Why […]
