Hi Sudarshan:
Did you have the thickness by now? If no, you may calculate it with the formula: e = p* D / 2 sigma p= max. penstock presure multiplied by a factor about 2 (for water hammer prevention) in (kg/cm2) D= diameter in (cm) e= thickness (cm) sigma= design working stress....for commercial steel SAE 1020 or 1030 you can take some 800 kg/cm2.
