What is the maximum volume flow rate, in m^3/hr, of water at 15.6°C a 10-cm diameter pipe can carry such that the flow will be l
1 answer:
Answer:
Q = 0.00017597 m3/sec
Explanation:
given data:
temperature of water 15.6 degree celcius
diameter = 10cm =0.1 m
dynamix viscosity of water = .0011193 kg/m sec at 15.6 degree celcius
density of water at 15.6 degree = 999.07 kg/m3
for laminar flow REYNOLD NUMBER < 2000
maximum flow rate =area*velocity
Reynold number
v = 0.022406 m/sec
where Q is flow expressed in m^3/s
Q =0.00017597 m3/sec

Answer:
Explanation:
Given that :
The initial volume of water = 1000.00 mL = 1000000 mm³
The initial temperature of the water = 10° C
The height of the water column h = 1000.00 mm
The final temperature of the water = 70° C
The coefficient of thermal expansion for the glass is ∝ =
The objective is to determine the the depth of the water column
In order to do that we will need to determine the volume of the water.
We obtain the data for physical properties of water at standard sea level atmospheric from pressure tables; So:
At temperature the density of the water is
At temperature the density of the water is
The mass of the water is
Thus; we can say ;
⇒
Thus, the volume of the water after heating to a required temperature of is 1022400 mm³
However; taking an integral look at this process; the volume of the water before heating can be deduced by the relation:
The area of the water before heating is:
The area of the heated water is :
Finally, the depth of the heated hot water is:
Hence the depth of the heated hot water is
Answer:
a) the log mean temperature difference (Approx. 64.5 deg C)
b) the rate of heat addition into the oil.
