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
