Can we prefer screw compressor over centrifugal compressor for ammonai or CO2 service?
no we can,t use the screw comressor over the centrifugal copressor because for higher pressure we need closed area like closed impeeler which is not in screw compressor
How do you insulate a basement?
According to the U.S. Department of Energy, basements should be insulated with closed cell foam board applied directly against the wall. No wood studs,or fiberglas should be used in basements because when combined with typical basement moisture, they favor mold growth.
Which phenomenon will occur when the value at the discharge end of a pipe connected to a reservoir is suddenly closed?
A compression shock wave will travel back into the liquid at the speed of sound. In domestic water systems this is called "hammer".
How do you discharge high dc voltage capacitor?
When a capacitor is powered off in an energized circuit, the capacitor still stores a certain amount of electricity. When there are other loads or components in the circuit, they will slowly discharge, or they can be quickly discharged by short-circuiting with small resistors or wires (at low voltage). When the capacitor discharges, the two poles of the capacitor respectively carry a certain amount of charge, and the outside world and the capacitor form a closed loop (generally, the closed loop does not include a power supply). The excess electrons (negative charges) approach the positive electrode of the capacitor to form a current, so that the charges at both ends of the capacitor are neutralized. When the neutralization is completed, the electric field between the two electrodes of the capacitor disappears. However, this is in an ideal situation. The amount of terminal charge is exponentially neutralized towards zero, but not zero. Discharge requirements of capacitors After the capacitor is disconnected from the bus, it must be discharged through a discharge resistor or a special voltage transformer. Discharge should be performed between the lead wires of the capacitor and between the lead wires and the casing. The capacitor can be grounded after the capacitor is discharged. Before working on the capacitor, be sure to conduct a test discharge. This discharge is to place the discharge rod on the terminal of the lead wire of the capacitor for a period of time. Even if both sides of the capacitor device are grounded, in order to prevent residual charge on the capacitor, a test discharge must be performed, and each group of capacitors connected in parallel must be discharged. Special care should be taken when conducting inspection discharge of capacitors removed due to faults. Due to the damaged capacitor, the general grounding device may not function as a ground discharge due to a partial disconnection. If the capacitor device has an interlock device, it should be considered that only after the entire device is grounded, the small door of the capacitor bank protective fence can be opened.

Why the isolator should not closed with load?
Isolation switches can be closed with loads connected. The isolation switch should not be opened under load unless the switch is load rated. This information can be found on the isolation switch's cover as to the amount of current that can be safely interrupted.
What happen if discharge of centrifugal pump closed?
if the discharge of centrifugal pump is closed the pressure is built up in it and after some time it will burst up
When should a reciprocating compressor not be energized?
the discharge service valve is closed.
If the outlet valve for both centrifugal and reciprocating pump is closed which pump is damage first and why?
The reciprocating pump is damaged first. The closed outlet has no bad affect to the centrifugal pump.
If you are in a No Discharge Zone what position is the Y valve in on your boat toilet?
It should be in the closed or inboard tank (if fitted) position
If suction valve of the centrifugal pump being closed in running what will be a effect?
It will damage the pump.
Can we prefer screw compressor over centrifugal compressor for ammonai or CO2 service?
no we can,t use the screw comressor over the centrifugal copressor because for higher pressure we need closed area like closed impeeler which is not in screw compressor
In chapter 7 bankruptcies is closed without discharge the same ad being dismissed?
No. Dismissed is essentially incomplete - no resolution...discharged is completed and closed.
What does it mean if someone asks if your bankruptcy is closed?
Normally when someone inquires if your bankruptcy is closed they are referring to has it been "discharged" When a judge presiding over the bankruptcy of a debtor and approves it. The approval constitutes a discharge of those debts and is thus "closed" On the other hand if the bankruptcy is not approved then the bankruptcy is "dissmissed" But in your case a closure constitutes a discharge.
Why would you still get your period after a complete hysterectomy?
You shouldn't as the uterus has been removed and the cervix or vagina closed b stitches. You nay get some discharge for a few weeks whilst the wounds heal however this should eventually stop altogether. If it is over two months or the discharge has bright red blood in it you should seek immediate medical help
What must you do in a No Discharge Zone if your boat has a y valve?
Be certain thet the Y valve is secuered in the closed position
Who wrote the Rise Against song Behind Closed Doors?
the person that wrote Rise Against- Behind Closed Doors was Savior. i hope this answers your question! :)
