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.
What is 'Ordinary Income'. Ordinary income is composed mainly of wages, salaries, commissions and interest income from bonds, and it is taxable using ordinary income rates.
