Question

Determine the initial volumetric flow of the water. The tank has a square base and is filled with water to the depth of y = 0.4 m . The 16-mm-diameter drain pipe is opened. (Figure 1) Express your answer to three significant figures and include the appropriate units 4 m Q2.19.10 Figure 1 of 1 SubmitPrev Previous Answers Request Answer XIncorrect; Try Again; 5 attempts remaining Part B Determine the volumetric flow when 0.2 m. Express your answer to three significant figures and include the appropriate units QValue Units

Explanation / Answer

a)

Area of a drain pipe is given by

A=pi*D2/4 =pi*(16*10-3)2/4 =2.01*10-4 m2

V=sqrt(2gy) =sqrt(2*9.81*0.4) =2.8 m/s

Volumetric flow rate of water

Q=AV =(2.01*10-4)(2.8) =5.63*10-4m3/s

b)

V=sqrt(2*9.81*0.2) =1.981m/s

Q=(2.01*10-4)*1.981 =3.983*10-4 m3/s
