`A 20cm diameter pipe of length 100m with z = 60m with f = 0.02 and loss of head due to entrance coefficient k = 0.5. What is the flow rate? Solution: Find the width in m of the channel at the back of a suppressed weir using the following data: H = 28.5cm; d = 2.485m; Q = 0.84 cu.m/sec. Consider the velocity of approach and use the Francis formula. Solution: Water flows in a 2m. wide rectangular flume at the rate of 2.75 cu.m./sec

the volume of the thoracic cavity‚ and the intercostal muscles contract‚ which makes the rib cage move upward and forward increasing the volume of the lungs. The increase in pressure inside the lungs makes the air from the atmosphere move into the lungs because air always moves from an area of high pressure to a low pressure area. During expiration‚ the intercostal muscles that lift the rib cage and the diaphragm relax. As a result‚ the rib cage and the diaphragm return to their original positions
