^^^ Boyze,
So your saying just assume the internal surface temperature of the enclosure is equal to the internal ambient air? Is that too conservative though, as this says there is no resistance between the internal air and enclosure?
Re- the original question on how to average the transfer...
Yeah I understand the true affects of what happens in the box is extremely complicated. It is a completely sealed enclosure and the size relative to the internal components is such that you could assume that heat flux is distributed evenly inside the enclosure.
The driving parameter for...
Hi All,
I have been working on how to calculate the maximum heat load allowed within a small rectangular alloy enclosure subject to natural convection only. I have calculated the heat transfer coefficient's for each of the internal and external surfaces (these are just plain flat surfaces at...
ahhhhhhh, thanks to all. I now understand.
In addition to the above theory, quality is the next determining factor to get the enthalpy of steam!!!!!!!!!!
given a pressure of 9kpa and an enthalpy at this point of 2370kj/kg. The temp is unknown. So from the theory stated, the pressure will give you temperature????.....but.....on this same line in the table the enthalpy does not equal the given value....hence wondering if the data is wrong? or my...
Hi All, first post here....
at the exit of a turbine in a power plant you have saturated steam at low pressure, eg 10kPa. It is stated that at pressure below 10kPa steam can be considered an ideal gas as the % error based on this assumption is minimal. Based on the pressure the temperature of...
