Sorry. I've uploaed a picture of the template of the diagram The t-s diagram is for a cogeneration system

Homework Statement . Can anybody help me to draw a T-s diagram Homework EquationsThe Attempt at a Solution Ive found out all the temperatures and entropy's but the videos I have watched don't help [/B] [/B]

Thanks alot! I think without connecting to mains it only last an hour or two.. Wonder if its worth getting one

Context of mini projectors. Yeah I think your right about the batteries but how could these batterys be charged without taking them out.. Not schoolwork. Just curios that's all

Im being very general. I am trying to find out what components are being used and what the power source is like.. There are many projectors but I want to just know the basic

Hi Im just wondering how mini projectors are powered up.. Is it a dc to ac ? Or just Ac? Also I am trying to look into a very small power supply but can't find anything as small as I want.. The smallest I've found is 13 x 5.6 x 9.7

Thank you

(ii) Efficiency of motor = Power output/power input, ð 0.85 = 12500/power input ð power input = 14706 WPower input = VImcosФ = (440)(I)(0.86) ð I am = 14706/(440)(0.78) = ð I am = 42.85 A The motor current I am is 42.85 A(iii) The current in the parallel capacitor leads the supply...

A 12.5 kW motor is to be powered from a 440 V, 50 Hz supply. Data from factory testing indicates the motor has an operating efficiency of 85% and that the power factor is 0.86 lagging. The power utility feeding the factory requires that the motor’s power factor is 0.96 lagging or better.(i)...

Cant you enlarge it by opening the actual picture? Sorry but I am new here..

Hi all Im trying to find the requirements of a switched reluctance motor but wih haven't found anything yet. Can anybody help?

Thanks alot

Thanks, but what do you mean by inert?

Thanks Can you explain what the reason is for this?
