Homework Help: Wave tank problem: Dimensional Analysis

  1. Oct 5, 2009 #1
    1. The problem statement, all variables and given/known data

    I am doing a project to build a scaled wave tank.
    "This project involves the design, construction and testing of a wave tank.
    When studying the hydrodynamics of a scale model or prototype, it is important to choose an appropriate scale.
    To determine tank and wave dimensions it is necessary to carry out dimensional analysis."

    Tank will have to mimic
    Avg. Wave Height 2.5m
    Avg. Wave Period 8secs
    Seabed depth of 300m

    I have room for up to a 10m long x 1m wide tank.

    I will have no problem in designing and constructing the tank once I know relevant dimensions.
    My problem lies in the using dimensional analysis to determine the dimensions of the tank and waves.
    I have not done D.A before and am lost as to where to even start.

    2. What to do now

    Any guidance of what needs to be done next would be apprieciated.
    Do I have all variables I need to determine the dimensions of the tank using D.A?
    Can anyone point me to relevant reading material/eqn's/info with regards to this problem and D.A?
