Complete the following sentences to determine whether the Be

Complete the following sentences to determine whether the Bernoulli equation is appropriate for calculating the pressure at B when the pressure at A is known. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. irrational can cannot ideal steady zero To use the Bernoulli equation, the fluid must be _______ and the flow must be _______. The Bernoulli equation can only be applied to points on different streamlines when the flow is _______ and the volumetric dilatation rate is equal to _______. Therefore, based on the velocity field, the Bernoulli equation _______ be used for the two-dimensional fluid flow shown in figure 1.

Solution

1. To use bernoulli equation , the fluid must be ideal and the flow must be steady .

2. The Bernoulli equation can only be applied to points on different streamlines When the flow is irrotational and the volumetric dilatation is equal to zero

3. Based on velocity field the bernoulli equation cannot be used for 2D flow

because the bernoulli equation is derived from the integration of eulers equation and euler equation is applied only for 1 d flow
