Why does wind accelerate as it flows over a Hillcrest?
Why does wind accelerate as it flows over a Hillcrest?
As a result, flow speed must be higher over the hils, and so there must be low pressure at the hillcrests to accelerate the winds. The bottom panel shows what happens when the wind is slower — the flow is subcritical.
Which is the correct gear to drive in when driving uphill?
If driving an automatic, and the standard ‘D’ is not giving you sufficient torque and power to climb, then you need to do the following: New AMT Car or DSG: Move the car gear lever to M and use “-” to shift lower. The real question should have been – Which gear to drive in when driving downhill?
What’s the best speed to go up a hill?
If you stay in third and have trouble getting up the hill, your vehicle may slip backwards when you try to downshift. Downshift to first at a speed of 10 to 15 mph (about 15 to 25 kph). Downshift promptly if you’re climbing the hill and start to lose speed.
Which is better to drive up or down a hill?
That said, manually downshifting can give you more control over your speed and is easier on your engine. An automatic transmission will downshift for you when you drive uphill. However, for moderately steep slopes, it’s wise to shift to the gear range marked D2, 2, or L to ascend and descend the hill.

What’s the best way to drive down a hill?
Drive downhill in a low gear instead of coasting or dragging your brakes. Whether you drive a manual or automatic, descend a hill using the same gear you used to climb it. If you drive a manual, shifting to neutral to coast down the hill is dangerous.
How is the throttle connected to the accelerator?
In the old days, there used to be a cable that was connected from the throttle to the accelerator. But now in the technological age, the car’s computer controls when the throttle opens and closes by the feedback it gets about the acceleration of the vehicle.
How to warm up and cool down for Hill repeats?
The warm-up should start at a low intensity and gradually build up with some short higher efforts to prime the legs. The cool down should be the reverse of the warm-up aiming to keep the cadence high to counteract the lower cadences of hill reps.
