The Bernoulli's equation in an ideal case gives the total pressure in a fluid flowing in a stream. The total pressure is a sum of three different pressures as follows
P+pv2 + pgh = constant
where p is static pressure, pv2 is dynamic pressure depending on the velocity of fluid v and pgh is hydrostatic pressure depending on altitude of fluid h. Inside the terms p is density of fluid and g is gravity acceleration. The equation means practically that the total pressure in a pipe at point 1 is the same as at point 2 despite the formation of the pipeline.
The fourth floor of a building is on fire. If the hose is spread along the fourth floor horizontally, which of the pressures has zero pressure difference between two points on the 4th floor, independently of the shape of the hose or its internal diameter? IChoose the most obvious alternative.
O dynamic pressure
O
static and dynamic pressure
hydrostatic pressure
