Question

Consider an air solar collector that is 1 m wide and 4 m long and has a constant spacing of 3 cm between the glass cover and the collector plate. Air flows at an average temperature of 45⁰C at a rate of 0.12 m3/s through the 1-m-wide edge of the collector along the 4-m-long passage way. Disregarding the entrance and roughness effects and the 90⁰ bend, determine the pressure drop in the collector.

Answer 1

To calculate the pressure drop in the air solar collector, you can use Bernoulli's equation. Find the velocity of the air flow, use Bernoulli's equation to find the pressure at the entrance and inside the collector, and calculate the pressure drop.

Step-by-step explanation:

To determine the pressure drop in the air solar collector, we can use Bernoulli's equation, which relates the pressure at two different points in a fluid flow with the velocity and height of the fluid. In this case, we'll compare the pressure at the entrance of the collector to the pressure inside the collector.

1. Calculate the velocity of the air flow using the given flow rate and the cross-sectional area of the collector.
2. Using Bernoulli's equation, find the pressure at the entrance and the pressure inside the collector. The pressure drop is the difference between these two pressures.
3. Substitute the values into the equation and solve for the pressure drop.

Based on the given information, the pressure drop in the collector can be determined.
