You are watching: The density of a liquid is to be determined by an old

**muzic-ivan.info:**

The thickness of the unrecognized liquid is 1.025 kg/m³ (considering the density of the water as 1.000 kg/m³)

**Explanation:**

The hydrometer functions by the Archimedes principle. The cylinder floats in the liquid bereason the hydrostatic thrust is equal to the weight force. This means:

If we measure 2 fluids, the weight of the hydrometer is the very same, so:

If the original watermark elevation is 12.3cm (H₁) and also the note for water has risen 0.3 cm above the unwell-known liquid–air interface, the elevation of the unwell-known liquid note is 12cm (H₂). Therefore:

Nitrogen (N2) at 1 bar, 300 K enters a compressor operating at steady state and is compressed adiabatically to an leave state of

GrogVix <38>

**muzic-ivan.info:**

a) 358.8 KJ/kg

b) 0.0977 KJ/K- kg

c) 83.28%

**Explanation:**

N2 at 300 k. ( usage the properties of N2 at 300 k (T1) )

Cp = 1.04 KJ/kg-k , Cv = 0.743 KJ/Kgk , R = 0.1297 KJ/kgk , y = 1.4 ,

Given data:

T2 = 645 k

P1 = 1 bar , P2 = 10.5 bar

a)Determine the work-related input in KJ/Kg of N2 flowing

Winput = h2 - h1 = Cp( T2 - T1 ) = 1.04 ( 645 - 300 ) =** 358.8 KJ/kg **

b) Determine the price of entropy in KJ/K- kg of N2 flowing

Rate of entropy ( Δs ) = Cp*InT2/T1 - R*In P2/P1

= 1.04 * In (645/300) - 0.1297 * In ( 10.5 / 1 )

= **0.0977 KJ/K- kg **

c) Determine isentropic compressor effectiveness

Isentropic compressor efficiency = **83.28% **

calculated utilizing the relation below

( h"2 - h1 ) / ( h2 - h1 ) = ( T"2 - T1 ) / ( T2 - T1 )

where T"2 = 587.314

A lake is fed by a polluted stream and also a sewage outautumn. The stream and sewer wastes have a degeneration price coefficient (k) of 0.5/d

joja <24>

**Equipment :**

**Given :**

k = 0.5 per day

Volume, V

Now, input price = output rate + KCV ------------- (1)

Input price

The output price

= ( 40 + 0.5 ) x C x 1000

Decay price = KCV

∴

= 1.16 C mg/s

Substituting all worths in (1)

C = 4.93 mg/L
