Consider the streamlines over a circular cylinder as sketched at thefigure 3.26. single out the first three streamlines flowing over the topthe cylinder. designate each streamline by its stream function, vivianav3. the first streamline wets the surface of the cylinder, designate vanthe streamline above that is v2, and the next one above that is v3.assume the streamlines start out in the freestream equally spaced. hencethe volume flow rates between the streamlines are the same. thestreamline v2 passes through the point (1.2r,1/2) directly above the topof the cylinder. calculate the location of the point directly above the top ofthe cylinder through which the streamline y3 flows. comment on thespacing between the streamlines directly above the top.

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
