Enter your answer in scientific notation.   The discharge (Q) of a stream is the velocity (v) times the cross-sectional area (A): Q = vA.   What is the discharge of a stream with a velocity of 2.0 m/s  and a cross-sectional area of 55.7 m2?

The first and second question is connected. Please help me to answer.

Problem 5. A Venturi flume with a rectangular cross-section is used to measure the flow rate from a wastewater treatment plant (Fig. 5). Given that the water depth upstream of the throat is h1 associated with your calculation? 0.8 m, calculate the corresponding flow rate. What are the assumptions 1 m 0.6 m Figure 5: Plan view of a Venturi flume that is used to measure the flow rate out of a wastewater treatment plant.

36. Darcy's law gives us the volume flow rate-volume per time (for example, cubic meters per day, m³/day). Another way to express volume is on a per-unit-area basis. For example, if we have a 1-m’ cube, we know its 3 3

A pump system is used to move water at a flow rate of 30 L/s from a lower to a higher reservoir in a city with an elevation of 1000 m above sea level. The system is shown schematically in the figure below, with ∆?=30 m. Both the suction and delivery pipes have a diameter of 150 mm and an absolute roughness of 0.3 mm. The lengths of the suction and delivery pipes are 6 and 500 m respectively. Ignore local losses and assume a temperature of 15 °C.  a)Develop a mathematical expression for the system curve (i.e. the pumping head required as a function of the system flow rate) from basic principles. Name all mechanics principles implemented. b)Calculate the required pump working point. What is the flow regime of the pipe flow.  c)What power does the pump add to the water in the system?

How do you find the average velocity of water leaving the tank?

Based in Chapter 1,2 and 4 Book: Viessman, W., Lewis, G., Knapp, J., Introduction to Hydrology, 4th Ed., Harper and Row 1. How would you apply the use of a Parshall flume in measuring the rate of flow in a small stream? O By estimating the volume of water passing through a specific point per unit time. O By calculating the velocity of the water flow using a velocity meter. O By measuring the width of the stream at various points. O By observing the depth (head) at the constricted throat of the flume, which produces a differential head that can be related to discharge.

The tank shown in the accompanying figure is being filled by Pipes 1 and 2. If the water level is to remain constant, what is the mass-flow rate of water leaving the tank at Pipe 3? What is the average velocity of the water leaving the tank? Pipe 1: di =1 in. V = 2 ft/s Pipe 2: d = 1.75 in. V = 1.5 fUs Pipe 3: d3 = 1.5 in. V = ?
