A model rocket is launched from point A with an initial velocity v0 of 86 m/s. If the rocket's descent parachute does not deploy and the rocket lands 104 m from A, determine
(a) the angle a that v0 forms with the vertical,
(b) the maximum h reached by the rocket,
(c) the duration of flight
Steam at 75kPa and 13 percent quality is contained in a spring loaded piston-cylinder device with an initial volume of 3.90m^3. Steam is now heated until its volume is 9.75m^3 and its pressure is 300kPa. Determine the heat transferred to and the word..
10 kg of cu and 10 kg of steel both at 95 c are dropped into identical tanks of water 10 kg 25 c 1 bar.a what is the
Why is this lab exercise useful? Where can the results be used in engi-neering design/industry - Prom your experimental setup what will be the maximum output power?
1-kg water in a frictionless piston-cylinder device is initially at 250 degrees Celsius and 300 kPa (state1). A total of 700 kJ of work is done on the water in order to isothermally reduce its volume to 1/20 of its initial volume (state 2). Determine..
Consider a sample of thickness L = 25 mm and a square planform of width W = 250 mm. In an experiment per- formed under steady-state conditions, temperature mea- surements made at the lower and upper surface of the sample yield values of T1 = 150°C..
an engine block with a surface area measured to be 0.90m2 generates a power output of 55 kw with a net engine
Water in the container is originally at a h=3 ft. If a block having a specific weight of 50 ib/ft^3 is placed in the water, determine the new level h of the water. The base of the blocks is 1 ft square, and the base of the container is 2 ft square.
water at 200 kpa and 10 degree celcius enters a mixing chamber at a rate of 150 kgmin where it is mixed steadily with
An electric locomotive together with its train has a mass of 200 tonne. The average tractive resistance to motion is 55 N/tonne while starting from rest up a gradient of 1 in 100. Calculate time taken to travel the first 1 km if the average tractive ..
why does turbulent flow distribution adhere more closely to the idealization of one dimensional flow than laminar flow?
many bridge designs today contain simple geometrical components but are constructed into complex ways to ensure that
1) An electron is shot through a magnetic field (see above) with an initial velocity of 100 ft/sec. The magnetic fieldaccelerates it in the perpendicular (normal) direction with a constant acceleration of 1000 ft/sec2. If the magnetic field has a d..
