Adhikari et al. (1991) studied the multi-stage
indirectly heated solar still.
They reported that the yield of a solar still is
always a prime design target. A rate of distilled water of
about 4.5 liters per square meter of solar collector per day,
typical of sloping roof still, is unfavorably compared with up
to 24 L/m2 of solar collector per day and even more for
multistage still.
This study aims to introduce the applicability of a
solar distillation model to determine the following:
1- The effect of meteorological variables on distillation
output (solar radiation, relative humidity, wind speed and
ambient air temperature).
2- The effect of model variables on distillation output (water
salinity, water depth, and cover thickness).
3- The relation between the distillation output and the
effective parameters.
