1. A float tool for controlling flow in tubing, the float tool comprising:
a housing configured to install on the tubing and defining a longitudinal bore therethrough;
a first valve disposed in the longitudinal bore, the first valve being configured to allow the flow in a downbore direction through the longitudinal bore and being configured to prevent the flow in an upbore direction through the longitudinal bore; and
a first inset disposed in the longitudinal bore upbore of the first valve, the first inset having an exterior surface disposed adjacent an interior surface of the longitudinal bore, the first inset having one or more first vanes extending inward to a central portion, the one or more first vanes forming a first orifice at the central portion and being disposed at a first angle relative to the longitudinal bore, the one or more first vanes being configured to produce turbulence in the flow in the downbore direction through the longitudinal bore.
