Answer:
A centrifugal pump is a rotating machine that pumps liquid by forcing it through a paddle wheel or propeller called an impeller. It is a most common type of industrial pump. By the effect of the rotation of the impeller, the pumped fluid is drawn axially into the pump, then accelerated radially, and finally discharged tangentially.
Explanation:
Suppliers generally offer charts in the plan, which present the various things at the nominal operating point using two main arrangements: the inductors and the balancing pants.
Answer: change the tires
Explanation: you can’t drive on a flat tire
Answer:
(i) 24.4 m
(ii) 2.19 s
(iii) -10.1 m/s²
Explanation:
(i) Kinetic energy = potential energy + work
KE = PE + W
½ mv² = mgh + Fd
We know the resistance force is 5% of the weight, so F = 0.05mg.
We know the slope of the incline is 1/30, so h = d/√(1²+30²).
½ mv² = mgd/√(1²+30²) + mgd
½ mv² = mgd (1/√901 + 1)
d = v² / (2g (1/√901 + 1))
Given v = 80 km/h = 22.2 m/s:
d = 24.4 m
(ii) Given:
Δx = 24.4 m
v₀ = 22.2 m/s
v = 0 m/s
Find: t
Δx = ½ (v + v₀) t
(24.4 m) = ½ (0 m/s + 22.2 m/s) t
t = 2.19 s
(iii) Given:
Δx = 24.4 m
v₀ = 22.2 m/s
v = 0 m/s
Find: a
v² = v₀² + 2aΔx
(0 m/s)² = (22.2 m/s)² + 2a (24.4 m)
a = -10.1 m/s²
