The mean pressure is `(6K)/5`, which rain renders to vertical windshield of automobile, moving with constant velocity of magnitude `v=12m//s`. Consider that raindros fall vertically with speed `u=5m//s`. The intensity of rainfall deposits `h=2cm` of sediments in time `tau=1` minute: [ `rho=10^(3)kg//m^(3))` is the density of liquid] (Assume collisions are inelastic). Calculate `K`.
