This is the concept of linear scale factors.
Diameter of hair strand is 0.00006=6×10^-5 inches
Diameter of sand grain is 1.3x10^-3 inches
Thus the the number of times the hair sand grain is bigger than hair strand will be:
linear scale factor=(diameter of sand grain)/(diameter of hair strand)
=(1.3×10^-3)/(6×10^-5)
=21 2/3 times

Answer:
143.26 sec
Step-by-step explanation:
Density = 4.3 g/l
Volume flow rate = 0.25 l/s
Mass flow rate = density x volume flow rate
= 4.3 x 0.25 = 1.075 g/s
This means 1.075 grams of the gas is released in 1 sec, therefore,
Time taken for leakage of 154 g of gas is
t = 154/1.075 = 143.26 sec
