计算题:从气压计上读得当地大气压是765mmHg,试换算成Pa,标准大气压和mmH2O。
正确答案:
因为1mmHg=133.322Pa
所以765mmHg=133.322×765=101991.33Pa
又760mmHg=1标准大气压
765mmHg=765/760≈1.007标准大气压又1mmHg≈13.6mmH20
765mmHg≈765×13.6=10404mmH2O
所以765mmHg=133.322×765=101991.33Pa
又760mmHg=1标准大气压
765mmHg=765/760≈1.007标准大气压又1mmHg≈13.6mmH20
765mmHg≈765×13.6=10404mmH2O
