Height rises only by spending pressure in a checked ideal budget. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Low outlet leaves pressure high

Speed stays v=4 m/s. Height h=0 m adds height term 0 pascals, leaving pressure 84 pascals.
