What are the two types of pumps?
Pumps are classified into two types namely Dynamic pumps as well as Positive Displacement Pumps.
What are the 2 types of compressor?
The two main types of compressors are dynamic and positive displacement. The positive displacement compressor is probably the one you’re familiar with. It traps gas in a volume and then decreases that volume. The decrease in volume causes a rise in pressure.
What is the principle of pump?
A Pump is generally used to induce flow or raise the pressure of a liquid. Centrifugal pumps are a category of Dynamic pumps. The working principle of centrifugal pumps involves imparting energy to the liquid by means of a centrifugal force developed by the rotation of an impeller that has several blades or vanes.

Why do we use multistage pump?
Multistage pumps are defined as pumps in which the fluid flows through several impellers fitted in series. This type of pump is often used in power station applications, e.g. as a boiler feed pump and in industrial applications requiring high pressures.
What is the major advantage of centrifugal pump?
The biggest advantage of centrifugal pumps is their aforementioned simplicity. They don’t require any valves, or many moving parts. This makes them easy to produce with many different materials. It also allows them to move at high speeds with minimal maintenance.
What is pump efficiency formula?
Pump efficiency is the “water horsepower” divided by the “brake horsepower” and multiplied by 100 to present it as a percentage (see formulas in Image 1). Water horsepower is a system design tool and is the power that the pump would require to accomplish the hydraulic conditions if it was 100 percent efficient.
What is manometric efficiency?
i. The ratio of the actual head developed to the velocity pressure of air moving at the fan-tip speed, equal to one-half the theoretical head of a radial-tip fan.
What is manometric head of a pump?
Total manometric head is the difference in pressure (in metres) between the pump’s inlet and outlet points.
How is overall efficiency calculated?
overall efficiency is = (power generated(calculated from voltage and current values) + mechanical power generated from the turbine (Pmech= torque * angular speed)) / (the total net power introduced into the system which is the heater’s power).
What is hydraulic efficiency?
Hydraulic efficiency (ηh) is also referred to as “vane efficiency” in the specialist centrifugal pump engineering literature and is the quotient of pump power output (PQ) and vane power (Pvane). P Power input of a centrifugal pump.
