Final answer:
The maximum slope of a taper bore for joining a thicker wall pipe to a thinner wall pipe depends on engineering standards and is not specified here, but it's designed to ensure a proper fit-up and to avoid stress concentrations. Bernoulli's principle and the continuity equation are used to calculate fluid dynamics in such a tapered system.
Step-by-step explanation:
The maximum slope of the taper bore when a thicker wall pipe is joined to a thinner wall pipe is not specified in the given information. However, the process of taper boring allows the diameters of two different pipes to become compatible for connection.
It's important for the taper to be gradual enough to avoid creating stress concentrations at the joint and to ensure a proper fit-up. The exact slope would typically be determined by engineering standards or codes relevant to the piping system in question.
When discussing fluid dynamics within a tapered pipe, such as water flowing from a larger to a smaller diameter, Bernoulli's principle is often used to relate pressures and velocities. If the taper is part of a fluid system, the gauge pressure difference required for water to emerge at a certain speed from the small end above the large end of the pipe can be calculated using this principle, together with the continuity equation and energy conservation considerations.
