Question

Given a two-dimensional steady inviscid air flow field with no body forces described by the velocity field given below. Assuming the density is constant find the pressure gradient in the x direction at a certain point specified by (x=3, y=2).
u = 2x

v = 3x - 2y

Answer 1

Answer:

the pressure gradient in the x direction = -15.48Pa/m

Explanation:

• The concept of partial differentiation was used in the determination of the expression for u and v.
• each is partially differentiated with respect to x and the appropriate substitution was done to get the value of the pressure gradient as shown in the attached file.
