What is negative reinforcement in slabs and beams?
the reinforcement which provided at negative moment developed section.
What is priming in the centrifugal pump?
The centrifugal pump has to be filled with fluid before it can start to move fluid. They cannot suck fluid in by creating a vacuum in the pump chamber like some other types of pumps.
What is downward heat flow?
negative heat
What is a wet kit on an excavator?
The wet kit is the water pump/radiator on excavator
Power required to drive a centrifugal pump is directly proportional to?
Cube of diameter of its impeller
Define the term negative slip in reciprocating pump?
When the actual flow (Qa) is greater than theoretical flow (Qt) in a reciprocating pump it is negetive slip.
Which pump is more efficient Centrifugal pump or reciprocating pump?
positive displacement pumps will always be more efficient than centrifugal pumps due to a centrifugals inherent internal fluid slip recirculation and losses.
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.
What are the advantages of a reciprocating pump?
we can pump water in high current
What is the difference between a single acting reciprocating pump and a double acting reciprocating pump?
it runs without fluctuation i.r continuous flow......
Is receiprocating pump advantageous or centrifugal pupm?
A reciprocating pump is an advantageous pump. Centrifugal pumps convert energy into rotation to power themselves. A reciprocating pump uses a back and forth linear motion.
How does a windmill pump water?
As the reciprocating pump operates through the reciprocation of the follower, it guides the suction and the compression of the water in the pipe. That's so when the rotary motion of the rotor blade is converted into the reciprocating motion, which delivers it to the reciprocating pump, the suction and discharge takes place.
How does a windmill pump water from the ground?
As the reciprocating pump operates though the reciprocation of the follower,it guides the suction and the compression of water in the pipe.That's so when the rotary motion of the rotor blade is converted into the reciprocating motion, which deliver it to the reciprocating pump, the suction and discharge takes place.
Shutting the discharge of an air operated reciprocating pump will cause the pump to do what?
stall
Why air vessel not fitting on reciprocating pump?
air vessel are use in reciprocating pump for to damped out the pressure variation during discharg so it is not fiteed on discahrg pipe the high pressure damp the pump
Why reciprocating pump is called positive displacement pump?
because they deliver a fixed quantity of the discharge irrespective of their rpm
How flow is continuous in single acting reciprocating pump?
momentum.
