Answer:
3150 L/min
Explanation:
The volume of the room is the product of the height of the room and its area. It is given as:
Volume (V) = height (h) × Area (A)
V = h × A
Height = 2.7 m, Area = 200 m². Hence:
V = h × A = 2.7 × 200 = 540 m³
The flow capacity (
) is given by
ACH = air changes per hour = 0.35
But 1 m³ = 1000 L, 1 hr = 60 min
Answer:
The flow of the electrons gets slower the more resistance added
Answer:
Explanation:
The determination of any further properties requires the knowledge of two independent properties. (Temperature and specific volume in this case). The specific volumes for saturated liquid and vapor at 140 °C are, respectively:
Since 
, it is a liquid-vapor mixture. The quality of the mixture is:
The specific enthalpies for saturated liquid and vapor at 140 °C are, respectively:
The specific enthalpy is:
Answer:
Because older cars didn't really have much power steering, and parking or even turning at low speeds could require a lot of strength to move the steering wheel on a big, heavy car. This moves the rack to the right or left, which turns the vehicle's wheels. Without power assist, you'd need grunt force to turn the pinion and move the rack.
Explanation:
According to the basic speed law, if conditions make it unsafe to follow posted speed limits, you should: Reduce your speed to less than the maximum posted speed limit.
<h3>What is the most speed limit?</h3>
The highest published speed limit in the country is 85 mph (137 km/h) and can be located only on Texas State Highway 130, a toll road that bypasses the Austin metropolitan area for long-distance traffic.
<h3>What is the 'rule'? </h3>
The 'rule' itself is quite straightforward: if the speed limit is (for example) 30mph, the rule notes that you won't get a speeding ticket unless you are going 10% plus 2 mph faster than the limit.
