The system below uses a centrifugal pump to circulate water at 19°C, having a vapor pressure of 2320 Pa, from a low reservoir to a higher one through a cast iron pipe with a diameter of 35 cm and surface roughness of 0.25 mm. The minor head losses upstream of the pump are represented by EK1 = 0,6 and downstream by & K2 = 7. After several months of usage, it is noticed that the installation is noisy and consumes...

Imagine a small town in which only two residents, Celia and Venya, own wells that produce safe drinking water. Each week Celia and Venya work together to decide how many gallons of water to pump. They bring the water to town and sell it at whatever price the market will bear. To keep things simple, suppose that Celia and Venya can pump as much water as they want without cost so that the marginal cost of water equals zero. The...

Water is pumped from a well to a water tower (an above-ground reservoir) through a 330 ft long galvanized iron pipe (ε-0.0005 ft) with a 2-in diameter. The water surface in the well is 10 ft below the ground and the water surface in the tower is 60 ft above the ground. The water is to be delivered at a rate of at least 370 L/min. The sum of the minor loss coefficients is 2.1 a) Using the pump performance...

6. (3 points) A water-based heating system is shown in Figure 5. A pump exerts a constant pressure difference between its inlet and outlet, ΔΡ-12 psi, to circulate hot water across 2 distinct paths. One path contains a single radiator that can be modelled as a pipe with an effective resistance to water flow of Ri-4x 107 kg-m-4 . s-1. The other path has two radiators with effective resistances to water flow given by R2-5x 107kg. m-4-S-1 and R3 3...

2. Cournot competition Aa Aa Consider a town in which only two residents, Sam and Amy, own wells that produce water safe for drinking. Sam and Amy can pump and sell as much water as they want at no cost. Assume that outside water cannot be transported into the town for sale. The following questions will walk you through how to compute the Cournot quantity competition outcome for these duopolists. Consider the market demand curve for water and the marginal...

Question 2 (a) A small electric vehicle is propelled by a motor with the performance data shown in Figure Q2 below. The motor drives a gear with 12 teeth, which in turn drives a larger gear, which is attached to the vehicle's driving wheels. The diameter of the driving wheels is 380 mm and the vehicle is designed for a speed of 30 km/h. (Note: Errors of +10% in reading data from the graphs are acceptable for the purposes of...

2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
(a) What is the force exerted to keep the car moving at constant
speed?
