Soloha48 [4]4 years ago
3 0

Answer:

Energy

Explanation:

The power of the driver (electrical motor for example), drives a piston in a positive displacement pump, or an impeller in a centrifugal pump.

Creates suction (pressure differential) which causes fluid to flow

Energy is converted to differential pressure.

A piston moves a 25kg hammerhead vertically down 1m from rest to a
UkoKoshka [18]

Answer:

Total change in energy = 31 KJ.

Explanation:

Mass m=25 kg

Height h = 1 m

Initial velocity = 0

Final velocity = 50 m/s

Energy at initial condition

E_1=mgh+\dfrac{1}{2}mv^2

E_1=25\times 10\times 1+0

E_1=250\ J

Energy at final condition

E_2=0+\dfrac{1}{2}\times 25\times 50^2

E_2=31250\ J

So the change in energy = 31250 -250 J

The total change in energy = 31000 J

2. A thin vertical panel L = 3 m high and w = 1.5 m wide is thermally insulated on one side and exposed to a solar radiation flu
n200080 [17]

Answer: 383.22K

Explanation:

L = 3m, w = 1.5m

Area A = 3 x 1.5 = 4.5m2

Q' = 750W/m2 (heat from sun) ,

& = 0.87

Q = &Q' = 0. 87x750 = 652.5W/m2

E = QA = 652.5 x 4.5 = 2936.25W

T(sur) = 300K, T(panel) = ?

Using E = §€A(T^4(panel) - T^4(sur))

§ = Stefan constant = 5.7x10^-8

€ = emmisivity = 0.85

2936.25 = 5.7x10^-8 x 0.85 x 4.5 x (T^4(panel) - 300^4)

T(panel) = 383.22K

See image for further details.
