Large storage tanks are designed to withstand low pressures and vacuums. typically they are constructed to withstand no more than 8 in of water gauge pressure and 2.5 in of water gauge vacuum. a particular tank is 40 ft in diameter.
a. if a 200-lb person stands in the middle of the tank roof, what is the resulting pressure (in inches of water) if the person’s weight is distributed across the entire roof?
b. if the roof was flooded with 8 in of water (equivalent to the maximum pressure), what is the total weight (in pounds) of the water?
c. a large storage tank was sucked in when the vent to the outside became plugged and the operator turned on the pump to empty the tank. how did this happen?

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
