The world has been hit hard by the latest COVID-19 pandemic, and health services and authorities in every country are struggling to reduce spread, fight disease and protect the population. Strict restrictions on movement, social distance and locking in certain cities have been imposed on people and businesses since the outbreak in Wuhan, China in December 2019. However, these widespread lockdowns, social distances and restrictions have led to major changes in human activity and have therefore produced some jarring effects across land, air and sea. Based on your knowledge, you can concisely describe the effects of the COVID-19 pandemic on our environment and discuss the effects on human activity, the current status of pollution and ways to mitigate pollution. The explanation should reflect to the THREE type of pollutions below:

  1. Nose pollution
  2. Soil pollution
  3. Air pollution

Question 4

Travel time of a 4ha catchment of a residential land use (C10 = 0.32) in Adelaide is 20 minutes. If the catchment area is equally divided into four parts by the 5-minute isochrones, compute 100yr design flood peak at the catchment outlet. What is the runoff volume generated from this storm event? Compute equivalent ΓΈ index of 100-year design storm event for this catchment.

assuming that the flow pattern is laminar flow rate of 200 gal/ min through a drill string having a 3.826-in. id and through an 8.5-x 5-in. annulus, calculate the required mud volume using 20% as volume safety factor given that depth of drill well = 10000 ft, length of drill collars= 500 ft, OD of drillingcollar= 6.5 in, ID of drilling collar = 2.25 in, casing setting depth = 5000 ft , case ID= 8.681 in, OD of drillpipes = 5in , ID of drillpipes = 3.826in


also it is desired to increase the weight of the mud from 12.0-lb/gal to 14.0-lb/gal mud. to keep the new mixture from becoming too viscous, 1 gal of water is to be added with each 100- lb sack of barite. a final mud volume of 700 bbl is required. determine the volume percentage of inital mud that should be discarded and the weight of barite to be added
