How is 1200/Sq Root of L = 120 comes out to L = 100.
11.65 Steam as water vapor at 100 kPa, 120°C comes out from a pipe into the atmosphere. Assume it mixes adiabatically with the ambient air at 100 kPa, 20°C, 45% relative humidity so the final mixture has an absolute humidity of ? = 0.01. Find the final mixture temperature and relative humidity
Example Suppose you are a small business and you currently rent 1200 sq ft. of office space at $22.50 a sq ft per year. In this cost, office cleaning is included. You are now looking at moving to a bigger office space of 2500 sq ft, and the utilities of water and electric are included in addition to the office cleaning. Three years ago when you signed the lease, the inflation rate was 105. The current inflation rate is 120....
Suppose that out of 1200 students at your university, 100 are on a break and not taking any classes this semester. Which of the following mathematical expressions describes the standard deviation of the sampling distribution of the proportion of 50 students who are on a break? Select one: a. √100×120050 b. √10050×1200 d. √(100/1200)×(1100/1200)/50
Question three An enterprising entrepreneur produces widgets and has a production function given by q=sq root lk In particular, factory has k =25, where. Rental rates for k and l are given by w =v = $1. a. If the entrepreneur wishes to minimize short-run total costs of widget production, how much output be produced? b. Given that output is optimally allocated, calculate the short-run total, average, and marginal cost curves. What is the marginal cost of the 100th widget?...
(a) How much current flows in a 100 watt bulb when lit? Assume 120 volts and assume DC voltage. (b) What is the resistance of a 100 watt light bulb when lit? Assume 120 volts and a tungsten filament temperature of 1200° C when lit. (c) How much current flow in the bulb when it is first turned on and the temperature of the filament is 20° C? Use α-5.36 x 10-3 Co.1 for tungsten.
