A wastewater plant discharges 3 MGD of effluent with a dissolved oxygen concentration of 0.5 mg/L into a chloride-free river flowing at 50 cfs. Upstream of the wastewater treatment plant outfall, the river is saturated with oxygen an at a temperature of 46.4 Fahrenheit degrees (8 Celsius degrees). What is most nearly the dissolved oxygen deficit (in mg/L) in the river just downstream of the outfall caused by the wastewater treatment plant discharge?

hello, nice to meet you if you know the answer, what am i saying?

One of the benefits of working with chlorinated polyvinyl chloride (CPVC) pipe is that it can be cut with a variety of different tools that don’t require any electricity or heat. However, different cutting methods are preferred over others, depending on the application.

When cutting CPVC pipe, it is important to make a square, flat cut. An uneven cut limits the bonding area and weakens the fitting.

To help you make the best possible cut, we’ve put together the following dos and don’ts when cutting CPVC pipe in different situations.

 They're compact and can easily be used for both FWD and RWD vehicles. Allows for greater displacement than inline cylinder engines, typically meaning more power.
