1. An apparatus comprising:
a pipe defining a cylindrical cavity;
a first endcap enclosing the cylindrical cavity at a first end of the pipe, the first endcap comprising an end plate;
a second endcap enclosing the cylindrical cavity at an opposite end of the pipe from the first end, the second endcap comprising an end plate;
a means for filling the cylindrical cavity with a fluid sample; and
a vibrational sensor coupled to the end plate of the second endcap and communicatively connected to a water property measurement system, the vibrational sensor operable to, subsequent to the filling of the cylindrical cavity with the fluid sample, send a signal representative of sensed vibrations in the end plate of the second endcap to the water property measurement system while the end plate of the first endcap is excited, the water property measurement system configured to compute a frequency response function from the signal and determine a bulk modulus of the fluid sample based on the frequency response function.
