Answer:
The absolute air pressure, on top of reservoir is 3858.84 kPa
Explanation:
Given
Since
Also,
, hence
KL = 0.5 + 2 +0.2 = 2.7
Pressure loss of pipe =
f from Moody chart at μ = 1.307 × 10⁻³ kg/m·s and
Roughness ε = 0.00026 m whereby, relative roughness is ε/d = (0.00026 m)/ 0.02 m = 0.013
f= 0.042 and
Q = v·A = 1.5 L/s = 0.0015 m³/s
v = Q/A where A = π·(0.02²)/4 = 3.1416×10⁻⁴ m²
v = (0.0015 m³/s)÷(3.1416×10⁻⁴ m²) =4.775 m/s
Pressure loss of pipe, = 3733071.965 Pa
= 3858839.04 Pa
The absolute air pressure, on top of reservoir = 3858.84 kPa
Answer
The skateboarder applies pressure to the trucks and gives/releases pressure on the levers. Second, the wheels and the axles are also examples of simple machines. They help the skater ride, spin, grind, and do a bunch of other radical movements on a skateboard.:
