a. If the air is found to have a flow rate of 1200 cm3/s as it leaves the 4.00 mm diameter pipe, what is the velocity of the air in both segments of the pipe?

Answer 1

Hi

Volume / time = velocity × Area

A1v1=A2v2=1200cm³ /s

Use

if r1 = 2mm = 0.2 cm

Find A1= pi ×(r1)²

^{you can find V1 from}

^{v1= 1200/A1}

^{find A2 using} A2= pi ( r2)²

then v2 =1200/ A2
