Exercise1: 10marks
As shown, a round viewing window of diameter D  0.8m is situated in a large tank
of seawater
 S  1.08 .
The top of the window is 1.2m below the water surface, and the
window is angled at 60 with respect to the horizontal. Find the hydrostatic force acting on the
window and locate the corresponding Center of Pressure.
Exercise 2: 10marks
A general equation for a steady, two-dimensional velocity field that is linear in both
spatial directions (x and y) is:
V   u, v    U  a1 x  b1 y  i  V  a2 x  b2 y  j
where U and V the coefficients are constants. Their dimensions are assumed to be
appropriately defined.
1- Calculate the x- and y-components of the acceleration field.
2- What relationship must exist between the coefficients to ensure that the flow field is
incompressible?
3- Calculate the linear strain rates in the x- and y-directions.
