Question
The flow rate of Wood flowing through a small Wood vessel or IV where viscosity is an important factor is most accurately determined by using Bernoulli's law Stoke's law Poiseuille's law Continuity equation The continuity equation is used to obtain the flow rate in a pipe system and the velocities of the fluid through various sized pipes that are joined together. If a pipe system is carrying a fluid at a flow rate of Q = 0.5 m^3/s, what is the speed of the fluid through a section of pipe with a diameter of 20 cm? 4 m/s 8 m/s 16 m/s 32 m/s Two equations govern the drag of an object in a fluid. Which one is used when the velocity of the object is slow in the fluid and the flow is laminar? Drag = 12 pi eta Dv Drug l/2CpAv^2 A blood platelet drifts along with the flow of blood through an artery that is blocked. As the platelet moves from the wide region into the narrow region, the blood pressure increases decreases Stays the same drops to zero Hydraulic systems utilize pascal's principle by transmitting pressure from one cylinder (called a master) to another (called a slave). A certain hydraulic system is designed to exert a force 50 times as large as the one put into it. If the area of the inlet piston is 5 cm^2, what is the diameter of the large outlet piston? 250cm 17.8 cm 8.9 cm 15.8 cmExplanation / Answer
1) Correct option is (b)
2) correct option is (c)
Q =0.5 m^3/s , d =20 m , r =10 cm
from continuity equation Q = Av
0.5 =3.14*0.1*0.1*v
v =16 m/s
3) Correct option is (b)
4) Correct option is (a)
cross secontion relation A1>A2
from continuity equation Q = Av =constant
v1<v2
from Bernoulis principle P1+(1/2)pv1^2 =P2+(1/2)pv2^2
P1 >P2
5) Correct option is (b)
F1 = 50 F2
A1 = 5 cm^2
F1/F2 = A1/A2
1/50 = 5/A2
A2 = 250 cm^2
250 =3.14*d^2/4
d = 17.8 cm
