Water is flowing at a rate of 500 gal/min in a horizontal pipe. the pipe is 500 ft long and contains two standard 90° elbows and a swing-type check valve. the pressure drop in the pipe line is 0.85 psig. what would be the diameter of the pipe? [density of water is 1000 kg/m: viscosity of water is 1.002 cp; relative roughness of the pipe is 0.00015 ft

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

i'm assuming that the correct answer is indeed the first one/ "a"..

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg
