Bernoulli equation calculator

Enter your values. The answer and the full worked solution update as you type.

Result

Velocity at 28 m/s
Pressure at 2170 kPa
Flow rate15.71 L/s

Step-by-step solution

Continuity

v2 = v1·(d1/d2)² = 8 m/s

Bernoulli

p2 = p1 + ½ρ(v1² − v2²) − ρgΔz = 170 kPa

Key formulas

Continuity
A1v1 = A2v2
Bernoulli
p1 + ½ρv1² + ρgz1 = p2 + ½ρv2² + ρgz2
Flow rate
Q = A·v
Circle area
A = πd²/4

Practise Continuity & Bernoulli

A calculator gives the answer. In the exam you need the method: practise it with new problems, hints and worked solutions.
