Question

a pressure of 10 power 6 dyne/cm square is equivalent to

Answer 1

The dyne is a unit of force specified in the centimetre-gram-second (CGS) system of units.

$$1 \mathrm {d y n} = 1 \mathrm {g} \cdot \mathrm {c m} / \mathrm {s} ^ {2} = 1 0 ^ {- 5} \mathrm {k g} \cdot \mathrm {m} / \mathrm {s} ^ {2} = 1 0 ^ {- 5} \mathrm {N}$$ $$6 \mathrm {d y n e} / \mathrm {c m} = 6 * 1 0 ^ {- 5} \mathrm {N} / \mathrm {c m} ^ {2}$$ $$P = 6 * 1 0 ^ {- 5} N / c m ^ {2} * 1 0 = 6 * 1 0 ^ {- 4} N / c m ^ {2} = 6 * 1 0 ^ {- 8} N / m ^ {2} = 6 * 1 0 ^ {- 8} P a$$
