Can someone pls tell me how to model this equation in matlab.
M*C_p*dt_a/dt = (Q-(m*(h_w-h_s))-(rho_w*V_w*(dh_w/dt)));
Where M = 10
C_p = 385
Q = 2000
m_dot = 1
h_w = 104.86
h_s = 2707
rho_w = 1000
V_w = 10

A differential equation already is a model.
Do you want to model a model? So approximate the differneitial equation using one of the many techniques that exist to do so?
Seriously, I assume you want to solve it?

you need an equation for dhw/dt, then use a matlab ode solver to solve the equations. see https://www.mathworks.com/help/matlab/ref/ode45.html
