P-Delta is a non-linear (second order) effect that occurs in every structure where elements are subject to axial load. It is a genuine "effect" that is associated with the magnitude of the applied axial load (P) and a displacement (delta).
The magnitude of the P-delta effect is related to the:
magnitude of axial load P
stiffness/slenderness of the structure as a whole.
slenderness of individual elements

What is p-Delta Effect?
When a building in an earthquake leans over far enough the force of gravity starts to act on the portion offset from the initial position of the building pulling it down further. That extra pull is called a p-delta effect The P-delta effect also refers to the second order (i.e. non-linear) effect of forces on the structure. As a results of the displcement, the stiffness changes, which in turn changes the force to be different than the linear analysis. In a linear analysis, a stiffness matrix K can be defined such that d = K*f where f is the vector of forces and d is the vector of displacements. In a P-delta analysis, there are additional non-linear effects, whether based on iteration or an closed for m solution.
What is mean by pressure drop how can you measure the pressure drop?
Use a delta-p gauge

What formula can be used to calculate delta pressure?
Delta pressure can be calculated using the formula: [ \Delta P = P_1 - P_2 ] where ( \Delta P ) is the change in pressure, ( P_1 ) is the initial pressure, and ( P_2 ) is the final pressure. This formula is applicable in various contexts, including fluid dynamics and engineering, to determine the difference in pressure between two points in a system.
What is diaphragm delta p?
Diaphragm delta P refers to the pressure difference across a diaphragm, which is typically used in pressure measurement applications. It is the difference in pressure between the two sides of the diaphragm and is a key parameter in determining the output signal from pressure sensors.

What is the unit for position?
Unit is P=Delta D over V
Why can we substitute Mean Arterial Pressure for delta P?
Mean Arterial Pressure (MAP) can be substituted for delta P (the pressure gradient) in certain physiological contexts because it provides a useful average of arterial pressure over a cardiac cycle. Delta P is the driving force for blood flow, and MAP reflects the overall perfusion pressure that influences organ blood flow. In steady-state conditions, particularly in systemic circulation, MAP approximates the pressure difference between the arterial and venous ends of the capillaries, making it a practical indicator for assessing blood flow and cardiovascular health.
