Are prices an accurate measure of a good's total value? Yes, prices are an accurate measure of a good's total value. No, prices depend on the elasticity of supply and demand. No, prices reflect marginal value, not total value. No, prices are the total benefit consumers derive from all units consumed. Which of the following accurately explains why professional wrestlers earn more than nurses? The supply of professional wrestlers is small relative to nurses, and price is determined by marginal...
The discharge of a stream is directly related to the A) volume of water flowing past a given point in a channel in a given amount of time. B) cross-sectional area of a channel and the average stream velocity. C) average stream speed and frictional contact. D) channel geometry and frictional contact.
Q1. The stage-discharge data of a river are given below. Establish a stage discharge relationship to predict the stage for known discharge. Assume the stage value for a zero discharge as 20.50 m. Also determine the stage of river corresponding to a discharge of 2600 m3/s. Table 1: Stage discharge data Stage (m): 21.95 22.45 22.8 2323.4 23.75 23.65 Q (m3/s)100 220 295 400 490 500 640 Stage (m) 24.05 24.55 24.85 25.4 25.15 25.55 25.9 m3 /s) 780 1010...
Respon A scientist wishes to measure the concentration of methyl benzoate in a plant stream by gas chromatography. He prepares a sample of butyl benzoate to use as an internal standard. The results of a preliminary run, which used a solution known to contain 1.71 mg/ml, of methyl benzoate (peak A) and 1.88 mg/mL of butyl benzoate (peak B), are shown. The area of peak A is determined to be 326 and the area of peak B is determined to...
The volume of water that a stream moves in a given amount of time is known as the stream's discharge In general, stream discharge will be velocity. 1 square 1 square meter Stream B Stream A Velocity: 30 meters/second Velocity: 10 meters/second Consider the above figure depicting a side view of the cross-section of two streams Each square represents one square meter (1 m) Think about which one would have greater discharge. (Develop a hypothesis.) Now let's test your hypothesis....
The discharge from a spring is to be measured with a 90° V-notch weir. If the head observed on the weir is 5 cm., what is the theoretical discharge and actual discharge? Use a discharge coefficient of 0.58.
A Parshall flume is to be designed to measure the discharge in a channel. If the design flowrate is 1 m3 /sec, determine the width of the flume to be used such that the depth of flow immediately upstream of the throat under design conditions is 1 m.
