yun nga din yung alam kong equation sir eh hehe....
apparently parang sa thailand yata iba yung principle nila sa snorkels hehe...yung mga duma dive na Triton sa waistdeep na putikan you will rarely see na may snorkel hehe...well siguro iba naman yun talaga compared sa river crossing or any terrain na may mataas na tubig kaya di sila naglalagay ng snorkel...
But didn't it come to your mind sir that even though large amounts of air is coming through the snorkel...It may disrupt the proper Air and fuel mixture of the Combustion? or the engine has the ability to adjust the fuel amount being injected depending on the air coming in through the snorkel?
pasensya na sir...medyo hindi ko lang po talaga kabisado yung mga bagay pagdating dyan hehe...Which I think you are knowledgeable po So I might just take the chance on asking you...
