Biological oxygen demand (BOD) is a measure of the relative oxygen depletion effect of a waste contaminant and is widely used to assess the amount of pollution in a water source. The BOD in the effluent (Lcin mg/L) of a rock filter without recirculation is given by:
where L0is the influent BOD (mg/L), D is the depth of the filter (m), and Q is the hydraulic flow rate [L/(m2-day)]. Assuming Q = 300 L/(m2-day) plot the effluent HOD as a

The antenna that receives radio signals can be modelled as an AC current source, I.. The antenna is connected to a "Tank Circuit" that consist of an inductor with inductance L, and a variable capacitor, and then connected to the ground. When the capacitor is tuncd to the right value, a very high voltage Vo is generated to send signals through the Germanium diode, and the signals are passed into an amplifier system and then converted to sound in the speakers.
