(1) An aircraft flies at an air speed of 315 km/h at 2500 m elevation. Evaluate...
An altimeter on a low-speed general aviation aircraft reads 1500 m. The outside air temperature (OAT) is observed to be 7.4°C. The aircraft’s pitot tube measures the pressure of 87050N/m 1. Assuming no calibration is required, at sea-level and under ISA conditions, equivalent airspeed (EAS) and indicated airspeed (IAS) are the same. At any other altitude, equivalent airspeed will be less than indicated airspeed. However, below speeds of approximately 200 knots IAS and at altitudes below 10,000', the difference between...
1. A train at a constant 62.0 km/h moves east for 32.0 min, then in a direction 46.0° east of due north for 29.0 min, and then west for 42.0 min. What are the (a) magnitude and (b) angle (relative to east) of its average velocity during this trip? 2. A cart is propelled over an XX plane with acceleration components ax 5.5 m/s2 and ay = -2.3 m/s. Its initial velocity has components vox = 9.3 m/s and voy...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
