Answer:
1.52 x x (cm3 STP) / -s
Explanation:
This is a permeability problem ithat asked to compute the diffusion flux of water vapor through a 2-mm thick sheet of polypropylene. The permeability coefficient of H2O through PP is
38 x (STP)-cm / -s-Pa.
Thus, from Equation
J= x ΔP/Δx = x / Δx
here
P1= 2 kPa =2,000 Pa
P2= 11 kPa = 11,000 Pa
J = (38 X x (cm3 STP)(cm) / -s-Pa) (10,000 Pa - 2,000 Pa / 0.2 cm)
= 1.52 x x (cm3 STP) / -s
Answer:
C. Zinc Blende
Explanation:
Out of the three possible crystal structures, only Zinc Blends is the unit cell structures which have four formula. Units per unit cell.
Therefore Zinc Blende is the only possible unit structures of AX ceramic material.

Answer:
Accuracy basically refers to closeness between the measured value to the actual and standard value is known as accuracy. In the mathematics and engineering the accuracy basically tells that the nearest measurement value with reference to the actual true value.
According to the International organization of standardization (ISO), the accuracy referring to the consistent and true results.
Precision basically refers to the value whose results is consistent when the measurement are repeated more than two times. Precision value may be different from one another because of the occurrence of random error in the form of the observational error.
Answer:
D. Both Technician A and Technician B are correct.
Explanation:
In electric components, a color code in used on a component to identify their value and function.The value is an electrical value which could be for a resistor or capacitor. For example resistors are coded in ohms.A color code could show the rating of an electric component.For example a tight tolerance resistor will be color coded using three bands.
A. Double
Piping head loss is calculated by converting all fittings to equivalent length/distance of a specific interior pipe diameter.
