    Balloon Time Valve
AI Thread Summary
To calculate the time required to open the valve for inflating a balloon, the user needs to consider the flow rate of air through the solenoid valve and the pipe dimensions. The solenoid valve has a diameter of 2mm and the pipe is 3mm in diameter, with a length of 300mm. The pressure needed to inflate the balloon is 1 psi, and the user is exploring Bernoulli's Equation to relate pressure, flow rate, and time. Relevant parameters such as mass, temperature, and gas constant have been identified, but further calculations are needed to determine the exact time for valve actuation. The discussion emphasizes the importance of applying fluid dynamics principles to solve the problem effectively.

Homework Statement
I have a canister (0.15L Volume). This will be filled with compressed air.
A solenoid valve attached has a diameter of 2mm, and the air will flow through this into a pipe which leads to a balloon. The pipe diameter is 3mm, with a length of 300mm.
The pressure required to inflate the balloon past it's elasticity is 1psi, I believe.
My question is how do I calculate how long I'll need to open the valve for enough pressure to get through to pump the balloon to that point?

Any help would be appreciated.

Welcome to the PF. :smile:

Is this post really for schoolwork? If it's not for schoolwork, I could move it to the technical forums. If it is for schoolwork, you need to show your efforts to work on the solution before we can offer tutorial help. Thanks.
 
Thank you!
This is for an undergraduate project I am working on. I am pressurising a reservoir and attaching an electronically controlled solenoid valve to the tank, which I will actuate to release pressure via a pipe, to a balloon.

I have an idea that relates to Bernoulli's Equation and so far I have relevant information:

Using: Pg+12ρgv2g=Pa

With regards to: Pg=mMRT

I have worked out that I have the below:

m = 28.97
T = 25 Degrees C
R = 287 J/kg

I'm not sure if I'm on the right track here...
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
