Air is flowing at.1 lbf/sec at an elevation of 50 ft and a velocity of 50 ft/sec. What is the total potential and kinetic energy in Btu/hr? zero 300 Btu/hr 41 Btu/hr 1202 Btu/hr Air is flowing a...
1 Steam enters a well-insulated nozzle at 300 lbf/in.2, 600°F, with a velocity of 100 ft/s and exits at 60 Ibf/in.2 with a velocity of 1800 ft/s. For steady-state operation, and neglecting potential energy effects, determine the exit temperature, in °F OF
There are two graphs that needs to be made in this lab: 1. Total Energy Vs time with m = 20g 2. Total Energy Vs time with m = 40g A) Explain the nature of the plots .(Linear or non linear?) The expected slope is zero in both cases. Why? Explain with the use of law of conservation of energy. What is the significance of the intercept? B) Suppose you drew the Kinetic Energy Vs potential Energy graph: The expected...
L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...
Oscillator Energies 50 40 30 Energy [J] 20 B 10 X 0.2 0.4 0.8 1 1.2 0.6 Time (sec) A damped oscillator with mass m = 3 kg experiences a linear restoring force (spring force) and a linear drag force Fa = -b Vy where vx is the oscillator velocity. The plot shows energies (kinetic, potential, and total) as a function of time. What is the value of the drag coefficient b in kg/s?
Question 1 1 pts What is the kinetic energy of a man who weighs 980N who is riding in a car traveling 40 km per hour? Express your answer in Joules, but don't type the unit in the answer box. Round to the nearest whole number. (Careful with the units) 1 pts Astudent slides her 80.0-kg desk across the level floor of her dormitory room a distance 4.00 m at constant speed. If the coefficient of kinetic friction between the...
