Consider an air solar collector that is 1 m wide and 5 m long and has a constant spacing of 3 cm between the glasscover and the collector plate. Air flows at an average temperature of 45°C at a rate of 0.15 m3/s through the 1-m- ideedge of the collector along the 5-m-long passageway. Disregarding the entrance and roughness effects, determine the pressure drop in the collector
If the side of the platform is a and the stiffness of each wire is k, determine the period of vertical vibration of the platform.
a prototype 90 degree pipe elbow has ethyl alcohol at 20 degrees celsius flowing through it. the pressure drop through
Design a ceiling diffuser. Air flows in the duct behind the diffuser and enters the diffuser at a pressure of 12.8psia, and a velocity of 200in/sec. The outlet of the diffuser is in the room, with atmospheric pressure of 14.5 psi. For the comfort of ..
A rigid container with volume V is originally filled with water of Temperature T1. A hose is then connected to an inlet port and hotter water of temperature T2 is pumped into the container at mass flow rate m in., while another venting port allows th..
Briefly discuss the importance of Structural Mechanics in Mechanical Engineering? List four different types of loadings that can be applied on mechanical structures or components
A piston-cylinder device initially contains 0.007m^3 of nitrogen gas at 130kPa and 120C. The nitrogen gas is now expanded polytropically to a state of 100 kPa and 100C. Determine the boundary work done during this process. I know I need to use the fo..
A dragster comes off the start line with an acceleration of 4 m/s2. The acceleration increases uniformly from 4 m/s2 to 10m/s2 over 3 seconds, then remains constant to the finish line (500m). Find: a) the acceleration as a function of time (make a gr..
Calculate the displacement and momentum thickness for the preceding velocity profile and compare with the exact results.
sun a 5800 k transfers heat to earth at an average rate of 1360 w per m2 of surface area of earth. the earth has a
What is the speed of the inertial frame in which the total momentum of the system is zero?
The tip of a 2-m-long slender rod with lateral surface insulated is dipped into a hot liquid at 200?C. What differential equation describes the temperature? After a long time, what is the temperature distribution in the rod if the other end is hel..
Determine the flow coefficient and stage loading factor at the mean radius and the reaction at the hub, radius 0.31 m, at the design speed of 8000 rev/min, given that stage is to have a free-vortex swirl at this speed. You may assume that losses a..
