At 0 m (sea level), where New Orleans lies, barometric pressure is around 101.33 kPa. The city of Chihuahua in northern Mexico has an altitude of 1433 meters (4698 feet) above sea level. At such altitude, pressure is around 86 kPa.
Let me differentiate first between design pressure and mechanical design pressure. Design (or discharge) pressure is the pressure at the outlet of the pump, the pressure you've designed the pump to deliver. The mechanical design pressure is a value that the pump casing and downstream piping have to be able to withstand as a minimum*. I presume you mean design pressure as discharge pressure. In this case, differential pressure is the difference between the discharge pressure and the suction pressure (the pressure at the inlet of the pump**). * this is calculated taking into account that a pump would be working against a 'blocked discharge' or a closed valve in the outlet piping ** imagine a reservoir filled with liquid
The word pressure speaks to the force applied by something, like the fluid air, on something else. A difference in pressure between one area and another will cause air to move in response to that differential pressure. This will create a draft, a breeze, wind or other phenomenon associated with moving air. This idea is at the heart of weather formation and atmospheric dynamics, and, along with some Coriolis forces, shapes planetary weather.
The city of New Orleans and the state of Minnesota are both in Central Tine Zone. There is no time difference between the two locations.
what is a manometer? and what is application of manometer in industrial? A Manometer is a device which can be used to measure pressure of fluids(i.e liquids and Gases). PRINCIPLE: Manometers are those pressure measuring devices which are based on the principle of balancing the column of liquid(whose pressure is to be found) by the same or another column of liquid. They are of two types 1. simple manometers 2.Differential manometers simple manometers are those which measure pressure at a point in a fluid containing in the pipe or a vessel. On the other hand Differential manometers measure the difference of pressure between any two points in a fluid contained in a pipe or vessel. Industrial applications: Pressure guages are used for a variety of industrial and application specific pressure monitering applications. visual monitering of air and gas pressure for compressors,Vaccum equipment and speciality tank applications such as medical gas cylinders, fire extinguishers,

its pressure between suction and discharge flow...
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
Differential pressure is the difference between two pressures. So, P2-P1.
A pressure differential switch, is a switch that reacts to pressure difference of two points, usually your supply & return side. If the pressure between these points are high, it then "reacts" notifying of pressure problem on the system.
Differential air pressure is a term of comparison. It may be stated as "the difference in air pressure between..." and finished from there. Let's look at a sentence and then break it down. "The differential air pressure across the body of the 747 is a cause of concern over the life of the aircraft." A jet at altitude has a pressurized cabin. The outside air pressure is very low. (Think Mount Everest. Almost no one climbs it without suplimental oxygen.) There is a difference between the air pressure inside the cabin and the air pressure outside the cabin. This is an instance of differential air pressure. The differential air pressure puts stress on the body of the plane. When the aircraft is back on the ground, the differential pressure disappears. The alternating application and neutralization of stress across the hull damages the structure over the life of the airframe. The differential pressure is the difference between the pressure of the air in the (pressurized) cabin at altitude and the pressure of outside air at that altitude.
Differential Pressure transmitters and level trolls
Differential pressure transmitters were originally designed for use in pipes to measure pressure before and after the fluid encounters a filter, pump, or another interruption in flow. Standard differential pressure transmitters come with two process connections arranged side by side to measure the drop in pressure (d) between the higher and lower points (H and L, respectively, in Figure 1). Classic differential pressure transmitters can also measure flow rates. It wasn’t long before people realized that differential pressure measurements could be used to determine liquid level as well.
Pressure Differential Valve- maintains a constant Differential pressure across it. Say if P1 was inlet pressure and P2 was outlet pressure PDV will try to keep constant DP. Say if P2 increases due to some reason and P1 is constant the DP will decrease and will decrease flow through the PDV. At this point to maintain the constant DP PDV will open and allow more flow through to keep the flow constant and thus DP constant.
It is defined as the instrument which can measure the difference between 2 pressure i.e high & low
