The formula for stoplog slot head loss is expressed as follows;

HL = (1/Cd^2 -1)*HV = (1/Cd^2 -1)*(V^2/(2g))
 
where,
HL : loss of stop log slot(m)
Cd : free-discharge coefficient
    (0.94-0.97 for type B slot)
HV : velocity head(m)
V : flow velocity(m/s)
g : acceleration due to gravity (9.8m/s^2)
