Problem

A hydrofoil plate of area

0.50\,\text{m}^2

is completely immersed in water. Water flows over the upper face at

3.0\,\text{m}\,\text{s}^{-1}

and along the lower face at

2.0\,\text{m}\,\text{s}^{-1}

. Given the density of water is

1000\,\text{kg}\,\text{m}^{-3}

, calculate the upward thrust acting on the plate.
