Estimate dissolved O2 after a flush

Share:

Description

Calculate the pO2 or [O2] in a respirometer after a flush. Given 5 of the 6 parameters, the 6th parameter is calculated.

Usage

1
flush_o2(resp_vol, flow_rate, duration, resp_o2, flush_o2, final_o2)

Arguments

resp_vol

volume of the respirometer (liter).

flow_rate

rate of water flow into the respirometer (liters / minute).

duration

duration of the flush (minutes).

resp_o2

O2 inside the respirometer before the flush (units do not matter as long as it is consistant with flush_o2 and final_o2).

flush_o2

O2 of the water used for flushing the respirometer (units do not matter as long as it is consistant with resp_o2 and final_o2).

final_o2

O2 of the water in the respirometer at the end of the flush (units do not matter as long as it is consistant with resp_o2 and flush_o2).

# What will be the pO2 in the respirometer after this flush?
flush_o2(resp_vol = 90, flow_rate = 10, duration = 3, resp_o2 = 15, flush_o2 = 21)

# I want to bring the pO2 back up to 95% air saturation. How long do I need to flush?
flush_o2(resp_vol = 20, flow_rate = 2, resp_o2 = 75, flush_o2 = 99, final_o2 = 95)
