What is the relation between flow discharge and time?
Flow discharge is the volume of water passing through a specific point in a river or stream in a given amount of time. The relationship between flow discharge and time is that flow discharge is typically measured in cubic meters per second or cubic feet per second, indicating the volume of water passing a point per unit time. As time increases, the cumulative flow discharge over that period also increases.
Bernoullis principle what characteristic of a moving fluid determines its pressure?
The speed of the fluid is what determines its pressure in relation to Bernoulli's principle. As the speed of the fluid increases, the pressure decreases according to the principle.
What is the relation between pressure and surface area?
Pressure is inversely proportional to surface area. This means that as surface area decreases, pressure increases and vice versa, given a constant force. This relationship is described by the equation: Pressure = Force / Area.
What is the relation between density and pressure?
The relation between density and pressure can be understood well with the help of the following derivation. Force = Mass x Acceleration →1 Pressure = Force / Area » Force = Pressure x Area →2 Equating 1 & 2 Pressure x Area = Mass x Acceleration Pressure = Mass x Acceleration / Area →3 Density = Mass / Volume » Mass = Density x Volume Eqn. 3 Becomes Pressure = Density x Volume x Acceleration / Area →4 i.e., Pressure is directly proportional to density.The relationship between density and temperature is the higher the temperature, the less the density.
What is the difference between centrifugal and axial compressor?
*Axial compressors are rotating, aerofoil based compressors in which the working fluid principally flows parallel to the axis of rotation. This is in contrast with centrifugal, axi-centrifugal and mixed-flow compressors where the air may enter axially but will have a significant radial component on exit. *Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiencies and large mass flow capacity, particularly in relation to their cross-section. They do, however, require several rows of aerofoils to achieve large pressure rises making them complex and expensive relative to other designs (e.g. centrifugal compressor). *Centrifugal fan/blowers are more suited to continuous-duty applications such as ventilation fans, air movers, cooling units, and other uses that require high volume with little or no pressure increase. In contrast, multi-stage reciprocating compressors often achieve discharge pressures of 8,000 to 10,000 psi (59 MPa to 69MPa). One example of an application of centrifugal compressors is their use in re-injecting natural gas back into oil fields to increase oil production. Centrifugal compressors are often used in small gas turbine engines like APUs (auxiliary power units) and smaller aircraft gas turbines. A significant reason for this is that with current technology, the equivalent flow axial compressor will be less efficient due primarily to a combination of rotor and variable stator tip-clearance losses. There are few single stage centrifugal compressors capable of pressure-ratios over 10:1, due to stress considerations which severely limit the compressor's safety, durability and life expectancy. *Compressor section location depends on the type of compressor. In the centrifugal-flow engine the compressor is between the accessory section and the combustion section; in the axial-flow engine the compressor is between the air inlet duct and the combustion section. *Centrifugal-flow compressors have the following advantages: * High pressure rise per stage. * Efficiency over wide rotational speed range. * Simplicity of manufacture with resulting low cost. * Low weight. * Low starting power requirements. They have the following disadvantages: * Large frontal area for given airflow. * Impracticality if more than two stages because of losses in turns between stages. **Axial-flow compressors have the following advantages: * High peak efficiency. * Small frontal area forgiven airflow. * Straight-through flow, allowing high ram efficiency. * Increased pressure rise due to increased number of stages with negligible losses. They have the following disadvantages: * Good efficiency over narrow rotational speed range. * Difficulty of manufacture and high cost. * Relatively high weight. * High starting power requirements (this has been partially overcome by split compressors).
Relation between power and discharge of a reciprocating pump?
The power required by a reciprocating pump is directly proportional to the discharge it produces. When the discharge increases, the power needed to maintain that flow rate also increases. This relationship is governed by the pump efficiency and the pressure head against which the pump is operating.
What does the relay do in a compressor?
the relay in the compressor helps it to respond to pressure increase or decrease process in relation to a gas.
Can you use a reciprocating compress replace a scroll compressor?
A reciprocating compressor is basically a piston pump, much like if you'd take an average internal combustion engine and force it to run. A scrolling compressor uses two plates with a spiral-wound raised ledge on them. The ledges overlap and as they move in relation to each other air gets squeezed further and further into the labyrinth until it reaches the outlet port.
Is there a preferred location on the AC lines where the service charge ports should be located?
The low pressure port is usually close to the compressor, on the larger of the two lines, and on the suction side of the compressor. The high pressure port is the smaller of the two and could be anywhere inside the engine compartment but usually along the firewall. The location of the hoses and ports depends on where the compressor is mounted in relation to the AC unit inside the car.
What does ZP stands for on a Sporlan TEV?
Someone please correct me if I am wrong, but ZP is in relation to the thermal expansion valve. This valve limits pressure and flow through the evaporator. Sporlan uses SZ and SZP to designate the thermostatic charge and is related to refrigerant r404a. Can anyone explain what the S is in relation to?
Has any relation between osmosis pressure and water activity?
There is definitely a strong relation between osmosis pressure and water activity. Osmosis is the movement of water from high pressure to low pressure.
What is the relation between pressure and friction?
Friction is directly proportional to pressure.
What relation is temp and pressure?
An increase in temperature leads to an increase in pressure.
What is the relation between pressure and force?
Pressure is defined as force per area
What relation between pressure and height?
Pressure decreases as height increases and vice-versa.
Does height have any direct relation with atmosphereic pressure?
yes.
What is the relation between force and preesure?
Pressure = force / area
