Hydraulics

Specific Foundation / Core

After the succefull completion of the course the students will be able to: (1) design and analyse pipes and closed conduits for pressure flow (2) determine the discharge capacity of pipes and closed conduits (3) design and analyse parallel pipes, pipes in series and hydraulic networks (4) determine pump characteristics and select pumps for pipew and hydraulic networks (5) design canals of various cross-sections and determine their discharge capacity (6) analyse flow in natural streams and rivers and determine their hydraulic characteristics (7) determine and analyse approaches for the energy dissipation of supercritical flow in open channels
