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.

differential phase-shift keying (′dif·ə′ren·chÉ™l ′fÄz ′shift ′kē·iÅ‹) (communications) Form of phase-shift keying in which the reference phase for a given keying interval is the phase of the signal during the preceding keying interval. Also known as differentially coherent phase-shift keying.

Cv is a capacity rating for a valve. A valve with a Cv = 1 will flow 1 gpm of water with a differential pressure of 1 psi. If the Cv was 100, it would flow 100 gpm of water with a 1 psi differential pressure.
For non-flashing/cavitating service, Q = Cv * (dP/SG)^0.5. Q is the flow rate in gpm (US gal), dP is the differential pressure in psi and SG is the liquid's specific gravity.

In absolute phase shift keying (PSK), the signal varies in phase relative to a reference phase, which remains constant for each symbol. In differential PSK, the phase difference between consecutive symbols is used to encode data, without referencing an absolute phase. This makes differential PSK more robust to phase shifts caused by factors such as variations in the transmission medium.

It is a device that measures the differential pressure between two inputs.
Example:
You have a pressure container where you connect the H-side (high) of the DP-cell. The L-side (low) you leave in the atmosphere (open air). The DP-cell will tell you the pressure in the pressure container relative to atmosphere pressure. Depending on what class the DP-cell is, it will give you feedback with a current signal. Normal in Europe is 4-20 mA, where 4 is lowest and 20 is highest.

Dp= rho * g * Dh Dp = differential pressure between point 1 and point 2 [Pa] rho = density of the liquid [kg/m3] g = gravity accelaration [m/s2] Dh= height from point 1 to point 2 [m] For typical everyday sizes of rho and Dh, it can be easily seen than Dp is in the range of 1 to 50 kPa (10 to 500 mabr)

Pros of differential phase shift keying (DPSK) include improved noise immunity compared to regular phase shift keying (PSK) because it changes signal phase differentially rather than absolutely. Cons include more complex demodulation due to the need to compare the current and previous signal phases for decoding. Additionally, DPSK may have higher bit error rates in certain scenarios.

Thin layer chromatography is a technique used to separate complex mixtures of compounds based on their differential partitioning between a stationary phase (thin layer of adsorbent material on a plate) and a mobile phase (solvent moving up the plate). As the mobile phase moves through the stationary phase, compounds in the mixture will separate based on their affinity for the stationary phase and the mobile phase.

DPSK (Differential Phase Shift Keying) is more robust against phase fluctuations during transmission compared to PSK (Phase Shift Keying). It eliminates the need for a phase reference, making it more suitable for noisy channels. Additionally, DPSK can provide better error performance in certain scenarios compared to PSK.

If there is a voltage differential from phase to phase, and a conductance (inverse of resistance) between them, then current (amperes) flows. This is no different than phase to neutral, i.e. voltage across conductance generates current, (I = EC, or I = E/A) except that neutral current is zero in a true phase to phase connection.
Note that phase angle is always relative. In phase to neutral, it is relative to (typically) neutral; while in phase to phase, it is relative to the other phase. By Fourier Analysis, the difference between two phases of the same frequency, but of different phase angles, is still a sine (or cosine) wave. Also, by Kirchoff's Current Law, (implied, and I will (sort of) not repeat it here), current entering from one phase and equally leaving via another phase will not reflect at all in the neutral conductor.
The simple answer is that connecting phase to phase is a short circuit, just like connecting phase to neutral.
CommentThere is no such thing as 'phase to phase' or 'phase to neutral'. The correct terms are 'line to line' and 'line to neutral'.

Thus, for 15.38 * 0.0045
The first number has 2 digits after the DP, the second has 4, so sum of digits after DP is 2+4 = 6.
1538*0045 = 69210.
The answer must have 6 digits after the DP so you need to insert a 0 after the DP to make it .069210 which can then be simplified to .06921
