Hi All,
I understand carbon sequestration in the simplest sense is capturing and storing carbon.
As seen in the title, I'm going to split this into two sections.
i) How does it work?
I imagine that trees, in a sense are doing this. They take in the carbon from our atmosphere and is stored...
Hi guys,
Bringing myself back up to speed with bolt tightening, would really appreciate if anyone has some resources or answers to these questions:
1. The proof load for torque tightening, and proof load for tension tightening
2. Main advantages and disadvantages between the two
3. What is...
Really appreciate the response.
Intuitively I did something similar. 1% of 7111.11 is 71.11 kg.
Therefore (71.11 + density of water in ambient conditions*V) / (Density of dry air * V)
> (71.11 + 0.00321* 7300 m^3)/(1.201*7300m^3)
= approx 0.00107 kg/kg airI figured if 71.11kg is...
Homework Statement
(Simplified)
During tests at cliffside power station, the following data was recorded from the cooling tower.
A cooling tower has a 9 cell draft design, each diameter is 10m.
Data
D_o = 10m
V_exit = 14.4 m/s
T_exit(15 celsius) = 288.15K
Ambient conditions : T(15 celsius) =...
Hey guys :)
So I'm looking to form equations that I can apply a Laplace transformation to. The mechanism specifically is a trailer jack - it converts rotational motion to linear motion. And its high torque provides a mechanical advantage to lifting heaving loads.
Can anyone help me form...
Hey guys,
Im studying for an exam and don't fully understand the jacobian process. Speciffically how you can differential the middle colum with respect to theta_3. Please view attached. So from step 1 to 2. Thanks.
Hello
So I've done some calculations, I'd like to see if my stuff is right. Thanks :)

area = (pi)(9^2) = 254.46
Cos53.13=15/CG
CG=25kN
Normal stress = 25000/254.46
=98.25
It's question 1b) Please view attached
1. Just to clarify, when different voltage sources are in series you pick the smaller one?
2. First step, they turned the 1A and 2ohm into 2V, why does the resistance disappear? Then between the last two steps the 12/7 ohm resistance remains with 18/7...

On line S=0.5*V*I why is the minus sign removed from in front of the "I" angle. 25.38 specifically. Could is be a typo?

Thanks a lot!
Do you recognise this formula...
W = PnR(T2/P2-T1/P1)
It's in the answers for a question, the question asked to calculate the work done by the air in a cylinder as it expands out. What's this equation, where is it derived from?
Firstly, let's assume the expansion is isentropic.
An example I found:
Mass flow = 0.5kg/s
Pi = 6000 kPa
Ti = 500 Celcius
Pf = 30kPa
From this, how do we find the power generated and final steam quality?
Do we look at steam tables, W = m(flow) (h_1 - h_2) --- is that helpful?
