Question

The rms speed of nitrogen molecules at 1200C is 50ms-1, calculate the rms speed
of nitrogen at 1500C.

Answer 1

We see from Table 3.1 that such an engine generates substantial second-order forces at twice engine speed or 1500c.p.m. Figure 3.7, redrawn from. Ref. 1, gives an indication of acceptable levels of transmitted vibration from the point of view of physical comfort. Figure 3.8 is a sketch of a typical seismic block.
