Question

D An Erlenmeyer flast of Surface area 0.5m² and wall thickness 2cm is filled with water at 0°C The Erlenmeyer Flask is then immersed in a glass beaker filled with water at a temperature of 30°C. what is the heat current?​

Answer 1

The heat current in the Erlenmeyer flask is 448.5 W.

What is Heat current?

Heat current or heat flow rate is the quantity of heat transferred in a given period of time.
$Q = \frac{kA \Delta \theta }{L}$

where;

• Q is the heat current
• k is thermal conductivity of water = 0.598 W/m.K
• L is thickness
• A is area
• Δθ is change in temperature

$Q = \frac{0.598 \times 0.5 \times (30-0)}{0.02} \\\\Q = 448.5 \ W$

Thus, the heat current in the Erlenmeyer flask is 448.5 W.
