Assertion : When an ideal fluid flows through a pipe of non-uniform cross-section, then pressure is more at that section where area is more if the pipe is horizontal. Reason : According to Bernoulli’s theorem speed at broader cross-section will be less. Assertion : When an ideal fluid flows through a pipe of non-uniform cross-section [...]
