The dimensions for the flow meters are given as follows. Note these values for future reference.

For Venturimeter

• Cross sectional area at throat of Venturimeter S₂ = 1.76 * 10^-4 m²
• The ratio of the diameter of throat to that of diameter of pipe β is 0.4848

For Orificemeter

• Cross sectional area to orifice meter S₂ = 1.54 * 10^-4 m²
• The ratio of the diameter of orifice to that of diameter of pipe β is 0.4904
