LEV needs to be at 1m/s at the face.
Let’s say area of LEV is .1 m2
What size plate (with holes or not in it) and weight is needed for the plate to fall off if the face velocity is less than 1m/s but the velocity is enough to keep the plate on the lev face if the speed is 1m/s or greater. I...
thanks for the reply.
I'm not sure if I have the thermal resistance figs, they may be given.
But, the study is comparing different types of floor.
concrete floor - no insulation
concrete - 80mm insulation
concrete - 250mm insulation
The Excel Data File will allow the following analysis to be conducted for both emitter types:
a) Calculate the variation in both the temperature drop across the emitter ( T) and total heat emitted (Q) over the entire test period for each of the 3...
Thanks for your reply, but I think you misunderstood.
We're just running a lab experiment to show how a variable speed drive saves money.
We want to run an AC pump at full throttle, then put a restriction in the pipe to reduce mass flow rate. Then we'll run the VSD at a lower speed with no...
We'll be running a vsd water pump. We'll be seeing the energy savings of using a vsd, instead of using an AC motor on full load and using a tap to reduce water flow. Sorry for the lack of info.
The Attempt at a Solution
I'm sure it will have something to do with...
sorry, the q is in m3/hr, so it would be .0055 l^3 / second.
The aim is to design the screw, work out the forces and design the thickness of the shaft etc.
Maybe this is the wrong forum.
The efficiency of an archimedes screw is 84%.
The main aim is to design a system that aerates a...
Or this? This is the one I used at first but I got a veeeeery small area, for a 20m3/hr flow rate and 1.75 head difference.
Would this be correct?
Ph = q ρ g h / (3.6 106) (1)
Ph = power (kW)
q = flow capacity (m3/h)
ρ = density of fluid (kg/m3)
