Homework Help - Transmitter for dP

AI Thread Summary
A differential pressure (dP) transmitter can be labeled as FT, PT, or LT in a process scheme because it can measure various parameters based on the application. For instance, a dP transmitter can measure flow by calculating the pressure drop across an orifice, pressure by measuring the difference between two pressure points, or level by assessing the pressure difference between a liquid's surface and a reference point. The versatility of dP transmitters allows them to serve multiple functions in different contexts. To effectively answer the homework question, it's important to provide specific examples and applications of how a dP transmitter can fulfill each role. Understanding these applications will help clarify the reasoning behind the labeling in process schemes.

Hello.

I've got a last homework before the summer, which is due to be handed in tomorrow.
The question is the following:

"How is it possible that a normal transmitter, used for measuring differential pressure, can get the label FT, PT, LT in a process scheme?"

Of course, the labels stands for Flow Transmitter, Pressure Transmitter and Level Transmitter.

Answers are appreciated!

Hello T4, ##\quad## :welcome: ##\quad## !

Different culture here at PF: we require an effort from the poster (see guidelines)

You also want to add some more context, because I'm pretty sure the answer "because paper is patient" , although correct, doesn't earn you any points.

Start by asking yourself: can a dP be used as one or more of the three ?
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
