Flash separations are fundamental to any process separation train. a full steady-state pro- cess simulation consists largely of many consecutive flash calculations. use unifac to determine the temperature at which 20 mol% will be vaporized at 760 mmhg of an equimolar mixture liquid feed of n-pentane and acetone.

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed.gi) ifn 1, what will happen to the material when transformed material when

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
