In the Bernoulli’s equation (\(\frac{P}{γ } + \,\frac{{{\upsilon ^2}}}{{2\,g}}\) + Z = constant, with notations : p - intensity of pressure, γ - unit weight of liquid, v - mean velocity of flow, g - acceleration due to gravity, Z - elevation above datum), each term in the equation represents:
1
energy in N.m/N weight of fluid
2
power in kW/kg mass of fluid
3
energy in N.m/kg mass of fluid
4
energy in kg.m/kg mass of fluid
