If the radius of a tube is decreased by 50%, the flow will be increased by 1/16 it’s original flow II. As the radius of the tube decreases from it’s original size, pressure increases to maintain the same flow III. If the radius of a tube is decreased by 1/16 it’s original size, the pressure within the tube will increase 2 fold IV. As the radius of the tube decreases, flow decreases from it’s original flow V. If the radius of the tube is decreased by 16%; flow will decrease by 50% it’s original rate
