Question
According to Hagen- law. the tube is defined as The radio of the pressure drop(dp) to the volume flow rate (f) and the resistance is proportional to the viscosity coefficient of the fluid flowing The radio of the volume flow rate(f) in that pressure drop (dp) and the resistance to proportional to the tube's length. The product density of the fluid (p) times speed of flow (v) and the resistance in proportional to the radius. The product of the volume flow rate(f) and the pressure drop(dp) the resistance is proportional to the fourth power of tube's radius. The water level in a vertical long glass tube can be adjusted to ary position in the tubes. A tuning fork vibrating at a frequency f in held just over the open top end of the like, to set up a standing wave of second it the air-field top position of the tube(that ari-filled top protein acts as a tube with one end closed and the other end open) Assume the sound speed in air equal to V_s The resistance appears if the distance between the water level and the top end of the tube it equal to (1/2 u/f) (1/4)rf r/f (1/4 r/f) An 500 kg object has a volume of .08 m^2. what will be its apparent weight when immersed in water? Assume acceleration of gravity equal to 10 m/s^2 4.0 10^-4N, 100N, 4200N, 5800N The density of blood is 1.06 times 10^2 kg/m^2 taking the blood's density the same as for water and acceleration of gravity equal to 10 m/s^2, what is the hydrostatic difference in blood pressure between the brain and foots in a tall person of height 2.0m? 2000 pa 20 kpa 200 pa 100 kpa When a body floats (neither rises nor sinks) in a fluid. The magnitude of the buoyant force acting on the body is equal the magnitude the gravitational force on the body. The weight of a liquid displaced by the body the body is greater than the magnitude weight a by the body. The magnitude the buoyant acting on the body is smaller to the magnitude of the gravitational force of the of The weight of a liquid displaced by the body is smaller than weight with a body. Water (as ideal fluid) is moving with a speed 5 0 m/s through a horizontal The of remaining area of 80 cm^2. The pipe decreases in area to 20 cm^2 horizontal speed at the greater area is 10 m/s. 1.25 m/s. 20 m/s 2.5 m/s. A piece of wood of mass m was attached to a massless string and set swinging. The period attached such a simple pendulum was equal T_p Afterwards the same piece of wood was attached spring and set oscillating with a period T_r The magnitude of T_p depends on m but T_r does not The magnitude of T_r depends on mi but T_p does notExplanation / Answer
2) resonace occurs when the distance is /4,3/4,5/4,...
= v/f
therefore, distance = v/4f
4) P = gh = (1.06*103)(10)(2) = 2.12*104 Pa = 20 kPa
7) in both cases it will depend on m
