Sentence examples for hour ventilation rate from inspiring English sources

All mice were housed in an environment of 23 ± 2°C, 54 ± 11% relative humidity, 10 15 air changes per hour ventilation rate, and 12 : 12 hours of dark and light cycle and provided with standard diet and purified water ad libitum.

VR was calculated while minute ventilation, ventilation rate and VCO2 were each varied in isolation.

The additional effective air changes per hour due to UVC at each ventilation rate were 4 to 19 times greater during winter than summer.

20 Figure 1 shows the modelled ventilation rate (air changes per hour) distribution for each scenario.

For the inhalation exposure rate, exposure via inhalation per hour was estimated as follows: where C A is the air concentration (micrograms per liter) and V is the ventilation rate for children (liters per hour).

Thermal comfort can be improved by an average of 2.5 °C (operative temperature difference for a change of 0.5 in albedo) but heating demand could be increased by 10% for a ventilation rate of 2 air changes per hour.

Relative humidity was kept at a constant level of approximately 50%%, room temperature was sustained at 22º ± 2 °C, and the ventilation rate was 15 20 air changes per hour.

Relative humidity was kept at a constant level of approximately 50%, room temperature was sustained at 22 °C ± 2 and ventilation rate was 15 20 air changes per hour.

From this it can be seen that while increased ventilation rates reduce the risk of transmission for all the infections, at high quanta production rates there is still a relatively high probability that infection will spread even at a ventilation rate of 12 air changes per hour.

From Figure 3 it can be seen that little impact is made on the transmission of TB and influenza by increasing the ventilation rate to 12 air changes per hour.

In a previous study (Johnson and Chiang 2015), we explored the implications of ventilation's impact on stove usage, finding that in comparison with the IWA 11 2012 ventilation rate of 15 ACH (air changes per hour), higher ventilation rates of 25 45 ACH would allow TSF usage for two to three times longer before WHO PM2.5 targets are exceeded.
