Q5. (a) Write down the Bernoulli's Equation and continuity Equation for a pipe flow and define each term in the equation. (b) The closed tank of a fire engine is partly filled with water, the air space above being under pressure. A 6 cm bore connected to the tank discharges on the roof of a building 2.5 m above the level of water in the tank. The friction losses are of 45 cm of water. Determine the air pressure which must be maintained in the tank to deliver 20 litres/sec on the roof.(a) Write down the Bernoulli's Equation and continuity Equation for a pipe flow and define each term in the equation.
