Fluid mechanics- Bernoulli's Equation along a streamline: The flow-metering device shown consists of a stagnation probe at station 2 and a static pressure tap at station 1. The velocity at station 2 is twice that at station 1. Air with a density of 1.2kg/m3 flow through the duct. A water manometer is connected between the stagnation probe and the pressure tap, and a deflection of 10cm is measured. What is the velocity at station 2?
Ariana was curious about the height of Mount Grande so she decided to climb it. She put a barometer at the bottom (before her trip), and at the top of the mountain. Assuming that the readings she got were taken at the same time, the barometer at the top reads 378 mmHg while at the bottom is 656 mmHg. Take the density of air to be constant at 2.46 kg/m3. What is the approximate height of the mountain (in meters)?
