6. A U-tube acts as a water siphon. The bend in the tube is \( 1 \mathrm{~m} \) above the water surface; the tube outlet is \( 7 \mathrm{~m} \) below the water surface. The water issues from the bottom of the siphon as a free jet at atmospheric pressure. Determine (after listing the necessary assumptions) the speed of the free jet and the minimum absolute pressure of the water in the bend. \( (10) \)
