AI Thread Summary
The discussion focuses on the mechanics of a nozzle utilizing the venturi effect to mix air with water. It explains that the water flow acts as the motive flow, creating low pressure that draws in air from the atmosphere as the suction flow. Key parameters include the flow rates (Q1 for water and Q2 for air), pressures (P1 and P2), and velocities (V1 and V2) of both flows. The participants are seeking to establish a relationship equation that connects these variables. The complexity of the question suggests a need for expert input to derive the appropriate equations.

Hi everyone, could you please help me in this:
There's a nozzle which use venturi effect to suck air from the atm and mix it with water. Say the water flow is motive flow (flow 1), and the air flow is suction flow (flow 2). The inlet water flow through a nozzle to increase its velocity (and thus decrease pressure), then enter a mixing chamber, the low pressure of the water flow cause air from the atm to be sucked to the mixing chamber through a second inlet. Say the motive flow (water) has flow rate Q1, pressure P1, velocity V1, and the suction flow (air) has flow rate Q2, pressure P2, velocity V2. What is the relation equation between them?
Thank you very much!

Thread 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Simple thought experiment with Stefan-Boltzmann law: energy'

Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (First part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8 and stuck at some statements. It's little bit confused. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. Solution : The surface bound charge on the ##xy## plane is of opposite sign to ##q##, so the force will be...
