   [Padmanabhan Ganesan] - Since your borewell depth is only 380 ft, 3 HP or less should be sufficient.
2. At what depth hv to put motor
   [Padmanabhan Ganesan] - Normally, the motor has to be placed 100 ft less than the borewell depth. So, 380 ft - 100 ft = 280 ft.
3. How many stage pu
   [Padmanabhan Ganesan] - Each stage consists of 20 ft. Depending on where you place the motor and to be on the safer side, i suggest atleast 13-15 stages.

Unless you provide Yield in Inches or Drawdown level of the Borewell. You can ascertain from the Drilling Operator

Since the bore well depth is 380 feet, it is suggested to install the pump at 350 feet for continuous water output. you have got 2 inches of water, you can choose 5 hp or 7.5 hp motor, this also depends upon your requirement, if you very less water you can even choose 3.3 hp motor, And regarding the no. of stages in pump, you can calculate the stages with 30 feet per stage, for you it comes to 12 to 15 stages, depending on the borewell place ground depression or elevation and pumping water above ground level to some height, example to overhead tank or storage tank.
