Wastewater of 30ft3/s with a biochemical oxygen demand (BOD) of 55mg/l, and dissolved oxygen (DO) of 3.3mg/l enters a river where the flow is 125ft3/s with an ultimate BOD of 7.0 mg/l, and DO of 6.8mg/l. The downstream has an average velocity of 0.8ft/s. i Calculate the minimum DO level and its distance in miles downstream using the oxygen sag equation. Assume k1 = 0.046 per day and k2 = 0.304 per day. The saturation DO = 8.5mg/l. (1 mile...

Biochemical oxygen demand i.e. BOD) is a measure of the potential damage that can be done...

Biochemical oxygen demand i.e. BOD) is a measure of the potential damage that can be done to the dissolved oxygen content of a body of water by organic waste. A BOD is also the amount of O2required to degrade or decompose the wastes. Its name comes from the "demand" that organic carbon has for O2 through biochemical (enzyme) oxidation. BOD – demanded oxygen – can be likened to a debt that must be paid. Dissolved oxygen (DO) can be thought...

During exercise, blood flow to skeletal muscles must increase to meet the increase in oxygen demand...

During exercise, blood flow to skeletal muscles must increase to meet the increase in oxygen demand for ATP (energy) production. The initial response that increases blood flow to the muscle cells is automatic and independent of the nervous and endocrine systems. Which type of homeostatic regulation is this? Explain.
