Bernoulli Equation

We remind ourselves that we cannot connect stations (1) and (2) with the Bernoulli Equation. But we just use the total pressure relation at (1) and (2). Accordingly,

$$p_1~+~{1 \over 2}~ \rho ~V_1^2~~=~p_{01}$$

$$~~p_2~+~{1 \over 2}~\rho ~V_2^2~~=~p_{02}$$ (3.116)

Total pressure loss is hence equal to

$$p_{01}~-~p_{02}~=~p_1~-p_2~+{{\rho \over 2}}(V_1^2~-~V_2^2)$$ (3.117)
