If 3600 j of work is done in 3.0 s what is the power0.00083W1200W3600W11000W
2 answers:
Answer : Power, P = 1200 Watts.
Explanation :
It is given that,
Work done, W = 3600 J
Time taken to complete the work, t = 3 s
The power is defined as the work done per unit time. The SI unit of power is watts.
Mathematically, it can be written as :
P = 1200 Watts.
So, the correct option is (B) " 1200 W ".
Hence, this is the required solution.

Answer:
Given that
Dry-bulb temperature(T) =24°C
Wet-bulb temperature(Tw) = 17°C
Pressure ,P = 1 atm
As we know that psychrometric chart are drawn at constant pressure.
From the diagram
ω= specific humidity
Lets take these two lines Dry-bulb temperature(T) line and Wet-bulb temperature(Tw) cut at point P
From chart at point P
a)
Specific humidity,ω = 0.00922 kg/kg
b)
The enthalpy ( h)
h=47.59 KJ/kg
c)
The relative humidity, RH
RH= 49.58 %
d)
Specific volume ,
v= 0.853 m³/kg
