Shell Balance
Rate of momentum in across surface at x (LW)(τxz)|x
Rate of momentum out across surface at x+∆x (LW)(τxz)|x+∆x
(momentum transport due to viscosity)
Rate of momentum in across surface at z = 0 (W∆xvz)(ρvz)|z=0
(due to fluid motion)
Rate of momentum out across surface at z = L (W∆xvz)(ρvz)|z=L
(due to fluid motion)
Gravity force acting on fluid (LW∆x)(ρg cosβ)
