Before starting the bending operations the hydraulic pressure / water level / flow switches etc. are checked. The pipe is now heated by induction to the temp of 815 - 995 C. By pushing the pipe by push clamp the bending of the pipe is started slowly and carried out at speed of 10 - 40 mm/min. The bending operation is stopped at the specified angle of bend and predetermined arc length.
For example; 'income' is a variable that can vary between data units in a population (i.e. the people or businesses being studied may not have the same incomes) and can also vary over time for each data unit (i.e. income can go up or down). A continuous variable is a numeric variable.
as an expense of the current period (see the bottom portion of the variable costing income statement). Variable manufacturing costs (1,000 units Ã $7 per unit) $7,000. The $5,000 difference in ending inventories explains the difference in net operating income reported. between the two costing methods.
