16 AM: Issue with the pump installation height
Thread Content
I can’t remember the exact title; it was something about determining whether a given pump could be used and what its installation height was. The options were: It can be used, with an installation height of -7.3； It can be used; the installation height is -3.5 ； It cannot be used. How did everyone choose for this question?
The vacuum level of this suction unit needs to be adjusted; it should be -7.3
Yes, I had correction too, and the result was -7.3
The vacuum level specified is for the operating conditions, not for the 20°C test conditions; no correction is necessary
What is given is the saturated vapor pressure at the operating temperature; the operating temperature itself is not specified. It seems to say that the saturated vapor pressure under operating conditions is 50.7 kPa.
The allowable suction vacuum level is also a operating condition
It’s hard to decide. What is the exact standard answer to this question?
Indeed, looking at it this way, there is a problem with this question. The given conditions are contradictory.
Don’t worry about it; getting one question wrong doesn’t necessarily prevent you from passing
