Well I'm doing a science progect. I have to make a poster. I need a catchy slogan about a lab saftey symbol. For example:Be wise and protect your eyes''. A symbol like.. Safety Goggles, Lab Apron, Poison, Fire, etc.. The teachers were helping students come up with those but since im an outcast and no one at all likes me. Based on how I Dress and what kind of music I listen to. No one likes me so I got no help. Thank You.
Yes a lightning rod should protect the building. There are standard codes for how to construct the rod properly.
The volume flow rate from the pipe is A*v π*0.080^2*3 0.0603m^3/s So each hose has a volume flow rate of 0.0603/3 0.0201m^3/s This translates to a mass flow of ρ*0.0201m/s 1000kg/m^3*0.0201m^3/s 20.1kg/s which is 20.1kg/s*3600s/hr 7.24x10^4 kg/hr per hose so the total mass flow 3*7.24x10^4 2.17x10^5kg/hr The speed in each hose is 0.0201m^3/s A*v so v 0.0201/(π*r^2) 0.0201/(π*0.020^2) 16.0m/s
