Vessel Characteristics

Vessel height: 11.6309 ft (3.55 m)Vessel Weight:

Operating, Corroded: 13,343 lb (6,052 kg)

Empty, Corroded: 3,481 lb (1,579 kg)

Vacuum, Corroded: 13,343 lb (6,052 kg)

Period of Vibration Calculation

Fundamental Period, T:

Operating, Corroded: 0.142 sec (f = 7.0 Hz)

Empty, Corroded: 0.067 sec (f = 14.8 Hz)

Vacuum, Corroded: 0.142 sec (f = 7.0 Hz)

The fundamental period of vibration T (above) is calculated using the Rayleigh method of approximation:

T = 2 * PI * Sqr( {Sum(Wi * yi2 )} / {g * Sum(Wi * yi )} ), where

Wi is the weight of the ith lumped mass, andyi is its deflection when the system is treated as a cantilever beam.
