1. T W DAVIES1 CONSERVATION OF MECHANICAL ENERGY FRICTIONLESS FLOW ALONG A STREAMLINE MECHANICAL ENERGY BALANCE ON A UNIT MASS OF FLUID –POTENTIAL ENERGY –KINETIC ENERGY –FLOW ENERGY

2. T W DAVIES2 THE BERNOULLI EQUATION THE SUM OF THE THREE FORMS OF MECHANICAL ENERGY PER UNIT MASS REMAINS CONSTANT IN A FRICTIONLESS FLOW p +  u 2 /2 +  gy = constant p/ (  g) + u 2 /2g + y = constant p/  + u 2 /2 + gy = constant

3. T W DAVIES3 BERNOULLI APPLICATIONS FLOW MEASUREMENT –PITOT TUBE (POINT VELOCITY) –VENTURI METER (flow rate in a pipe) –ORIFICE PLATE (flow rate in a pipe) –OPEN CHANNELS, WEIR FLOW (flow rate)

4. T W DAVIES4 BERNOULLI APPLICATIONS SOLUTION OF FLOW PROBLEMS –Example - THE SIPHON –Example - THE FOUNTAIN
