1. ### Fluid Mechanics problem: Oil pressure calculations in pipe flow

Okay great, I note that we have been given the viscosity in this problem, are we supposed to use it in this section? Am I correct in thinking that the incline at 40 degrees is somehow related to z1 and z2?
2. ### Fluid Mechanics problem: Oil pressure calculations in pipe flow

Sorry, I think misunderstood you. The steady flow energy equation should reduce to: p1/pg + z1=p2/pg +z2+hf I think this is correct for cases where the flow is zero.
3. ### Fluid Mechanics problem: Oil pressure calculations in pipe flow

It reduces to zero?
4. ### Fluid Mechanics problem: Oil pressure calculations in pipe flow

Ah sorry, I meant steady flow energy equation.
5. ### Fluid Mechanics problem: Oil pressure calculations in pipe flow

Thank you, can the sfee can be used instead?
6. ### Fluid Mechanics problem: Oil pressure calculations in pipe flow

Am I correct in my understanding? For the calculation, I will need to use the bernoulli's equation, is that right?
7. ### Fluid Mechanics problem: Oil pressure calculations in pipe flow

The pressure would still be 250kPa at the top end because pressure decreases with altitude.
8. ### Fluid Mechanics problem: Oil pressure calculations in pipe flow

Problem Statement: An oil with density 900 kg/m3 and viscosity 0.18 Ns/m2 flows through a circular pipe which inclines upwards at 40° to the horizontal. The length of the pipe is 10 m and the diameter is 6 cm. The fluid pressure at the lower end of the pipe is 350 kPa and the pressure at the...
9. ### Writing the Equations of motion

I have attached the problem and I have also taken a photo of my working for it, it seems my answer is wrong. I would be grateful if you could please check where I have gone wrong. Thanks a lot.
10. ### Damping questions

Hello everyone, I am really stuck on the first question in the document and I don't even know where to begin. If someone could explain what is happening and how to start the problem, I am confident I will be able to tackle it. It would also be a big help if you could direct me to some...
11. ### Dynamics Question

Mod note: Thread moved from technical section so no homework template shown. Hello there, I am working on a dynamics question, but I am not sure how to tackle it since my teacher has not really taught this topic well. I would like some advice on how to start the question off and the method...
12. ### Compound pendulum question

I won't be able to upload a sketch of the setup since my printer isn't working at the moment. Is it okay if I show you an accurate picture of the experiment and a picture of the graph? :smile:
13. ### Spiral Spring Experiment

One equation is: T=kx the tension force, T, in the spring is proportional to the extension x produced. and another equation is g=(e/m)xk The gradient of first graph gives the spring constant k and the gradient of the 2nd graph is (e/m) hence I think the gradients of both graphs give the value...
14. ### Spiral Spring Experiment

Hello everyone, I did an experiment titled 'mass on a spiral spring' in order to find the value for the acceleration due to gravity. The experiment consists of two parts. In the first part of this experiment, I just measured the oscillation period of a spring as a suspended mass and plotted...
15. ### Compound pendulum question

I am doing the compound pendulum experiment but I am stuck on how to find the value of g from the graph Here's a description of the compound pendulum: The compound pendulum AB is suspended by passing a knife edge through the first hole. The pendulum is pulled aside through a small angle and...
