Find the average air speed in the exit duct and express it in ft/min and m/s.

Question

A permeability test apparatus of diameter 82.5 mm contains a column of fine sand 460 mm long. When water flows through it under a constant head at a rate of 191 cm3/minute, the loss of head between two points 250 mm apart is 380 mm. Calculate the coefficient of permeability of the fine sand. If falling head test is made on the same sample using a standpipe of diameter of 30 mm, in what time will the water level in standpipe fall from 1560 mm to 1066 mm above outflow level.

LAB: FORCE AND FORCE-RELATED VARIABLES ASSIGNMENT INSTRUCTIONS INSTRUCTIONS Lab assignments are intended to give you some ‘hands on' experience in applying the concepts introduced in the course text. They are designed to get you out of your classroom or office and develop the skills of designing experiments and collecting data, and then performing calculations, evaluating the results, and communicating your findings. Labs are more than just number crunching - they are about reflecting on what is both practical and technically sound engineering problem-solving. For each problem below, address the scenario presented and develop engineering solutions. Communicate your results using drawings, pictures, and discussion, supported by calculations developed using the Microsoft Equation Editor or similar tool. Submit your lab report in a single pdf file uploaded to the location provided in Canvas before the due date/time indicated. Each problem should be treated as a micro-report with a problem…
