Water flows downward through a vertical smooth pipe (i.e., roughness = 0). When the flow rate is 0.5 ft3/s, there is no pressure change along the length of the pipe. What is the pipe diameter?
a large guinea pig weighing 2 kg is riding a skateboard horizontally at a speed of 25 ms. then a force causes the
heat is transferred to a cylinder having a fixed volume of 6 m3 containing 0.1 m3 of saturated liquid water and 5.9 m3
An oil company refines crude oil valued at $62/barrel and sells it to motorist as gasoline at its retail centers at a price of $2.90/US gallon (1 barrel = 42 US gallons). A supply disruption causes the price of crude oil to increase overnight to $100..
an air-conditioned room requires 30 m3 min of air at 1.013 bar 20 degree c 52.5 rh. the steady flow conditioner takes
5 kg of steam are initially at 310 bar and T = 750 C. The steam is isobaric ally cooled to 450 C. First, sketch the process on T -v and p - v diagrams. Then, determine Q, W, delta U, and delta H in kJ for this process using the steam tables.
How to calculate the force required to displace the Bellow for 10mm which is fixed in the pipe line. It is a ring type bellow and i want to find axial force.
a flow of 4 kgs ammonia goes through a device in a polytropic process with an inlet state of 150 kpa -20degc and an
Consider laminar flow of a fluid through a square channel with smooth surfaces. Now the average velocity of the fluid is doubled. Determine the change in the head loss of the fluid. Assume the flow regime remains unchanged.
Obtain a new solution, and determine whether any buckling constraints are active. If no buckling constraints are active for L = 10 in., re-run the analysis by increasing L , and estimate the value of L at which at least one buckling constraint b..
A 400 L rigid tank contains 5 kg of air at 25 C. Determine the reading on the pressure gauge if the atmospheric pressure is 97 kPa.
Calculate the change in velocity required in changing the position of a satellite in an orbit by 90 degrees. The initial and final orbit is circular around the Earth with a 15000 km radius. Calculate the delta velocity, semi-major axis and period for..
