Describe the main equipment, components and processes involved in the active continuous generation of x-rays in a modern digital radiographic imaging system .
a micro-focus 2d x-ray inspection is to be undertaken on a square (8mm x 8mm) mild steel plate of thickness 20mm. the source to detector distance is fixed at 0.5m and the detector is an array 2048 x 2048 pixels and dimensions 100mm x 100mm. the focal spot size of the x-ray tube is 30μm. a geometric unsharpness value (ug) of better than 0.01mm is required.
calculate the required source to object distance.

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

good luck: )
