What is Leonard Euler's famous formula?

eix = cos(x) + i*sin(x)

where e is the irrational number 2.7182...

i is the maginary sq root of -1

and x is measured in radians.

In the special case when x = pi, this reduces to:

eiπ = cos(π) + i*sin(π)

or

eiπ = -1

What is a system curve?

a System curve is used in hydrolic anylyses to dtermine the duty point of a pump for a certain pipe line.

The pump curve and system curve are plotted on the same graph and where the two cross each other is the duty point, the curve is a Head(meters) vs Flow(m3/hour).

The system curve

Head = static head + head loss due to friction in pipe + secondary head loss

*This is calculated for a certain flow to determine the Head so it can be plotted on the curve

All major engineering projects must be preceded by?

All major engineering projects must be preceded by a statement of work that describes the parameters and deliverables of the project.

A differential pressure transmitter is to be calibrated to read level of a closed vessel The dimensions of the closed vessel are as given below What would be the calibration range of the transmitter?

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)
