    Flow through a parallel piping network

    Hello all, How does one calculate the expected mass flow rate through a parallel piping system in which each pipe has different pressure drops? I have a refrigeration system with a hot gas bypass line installed, which connects the discharge of the compressor to the suction of the evaporator...

    flow in parallel plates

    Hello to everyone, I am attending a course of advanced fluid mechanics and i was given the following exercise in the attached picture which from what i understand should not be so tough. But since my knowledge is still very restricted, i had only basic fluids some years ago, how should i...

    Parallel pipeline flow rate

    Hello to everybody, The problem is given here: My diagram is here: Per problem question, do we need to find Q2 and Q3 which is governed by Q1=Q2+Q3? I am also stuck with the absence of data for viscosity and diameter. How to manage them? Can we express the equation given in the problem...

    How is it possible for parallel worlds to collide?

    Hi there. I'm new here and this is my first post. I'm interested in physics and cosmology, but I have very limited knowledge. In fact I just follow the news and read articles and watch movies (e.g. the fabric of cosmos). After watching the fabric of cosmos by Brain Greene, a problem...

    Are these capacitors in series or parallel?

    I need to find the voltage across the 2uF capacitor and I'm confused as to what they are ordered in. I'm also looking at the voltage after the loose lead is connected to the 2uF, so the second diagram.

    parallel combination of springs

    Let, two springs are connected with a mass in parallel combination. But this mass is situated in the middle of this two springs. When mass applies force to compress one end of one spring, other end of another spring will expand. I searched a lot in net for mathematical problems with solutions...

    Is the following a parallel or a series circuit?

    Imagine two copper plates 6" square with a single wire soldered to each plate. Now arrange several D-size batteries, as many as you can arrange standing up on their '-' ends, on one of the plates as it's laying flat on the table. Now set the other plate on top, so it touches all the '+' ends...

    Electric field in a parallel plate capacitor

    The Electric Field in a parallel plate capacitor is approximately constant between the plates of the capacitor. Why is this so? I imagine it is only true if the distance between the capacitor is small compared to the area of the plates or it may just be the opposite of that. Prove it...

    Dielectric Filled Parallel Plate Capacitor Question

    I recently had a test in my Physics class and I answered this question wrong. I'm trying to figure out the correct solution so I can keep it in my records for future reference. I'm unsure how to set this up, I can't seem to find a way to solve it without a given value of Q. "A parallel...

    frequency in series and parallel circuits

    When placed in series a coil and a capcitor resonate at a frequency of 2251Hz and when placed in parallel they resonate at a frequency of 2228Hz. At parallel resonance it is also found that a current of 5mA flows from the supply when the supply voltage is 25V rms. Determine the value of the...
