In a method of measuring a fluid volume flowing through a tube by means of the magnetic nuclear spin resonance, the magnetisable nuclei of the fluid volume are aligned by means of a magnetic d.c. field and synchronised by means of a magnetic alternating field. To achieve a measurement ...
The water flowing through the stationary housing urges an impeller to actuate the gear train. The gear train is essentially engaged with the control ring so that after a certain period of time the control ring is brought back to a configuration not allowing water to flow through the device. ...
Poiseuille's Law for blood flow says that the volume flowing through an artery is proportional to the fourth power of the radius, that is,. By how much must the radius be increased in order to increase the blood flow by 40%? [填空1] 答案:1、10% 手机看题 你可能感兴趣的试题 单项选择...
In a volume flow regulator for an adjustment flap (4), which regulates itself according to an air speed in a pipe section of a ventilation or air-conditioning system, the adjusting flap (4) is to have a rotary element (9) placed on it. In this case, there is connected to the rotary...
A volume V of a viscous liquid flows per unit time due to a pressure head DeltaP along a pipe of diameter d and length l. instead of this pipe a set of four p
, we need to calculate the average velocity in the pipe at location 1, where A 1 =πD 2 /4: V 1 = /A 1 = 2.457 m/s. V o Now we calculate the Reynolds number, Re = ρV 1 D/μ, where we use the properties of the flowing fluid, ...
