Steel products are commonly protected by chromium or zinc coatings. Based on the galvanic series, what difference would you expect in their ability to protect steel?
an engineer determines that a 40-cm-long rod of 1020 grade steel will be subjected to a tension of 20 kn the following
Steam enters a nozzle at 4 MPa and 640°C with a velocity of 20 m/s. This process may be considered reversible and adiabatic. The nozzle exit pressure is 0.1 MPa. (a) Draw a sketch of this process. Include all known information. (b) What is the entro..
a 1 kg block of copper at 350degc is quenched in a 10 kg oil bath initially at ambient temperature of 20degc. calculate
A commercial refrigerator with refrigerant- 134a as the working fluid is used to keep the refrigerated space at 235°C by rejecting waste heat to cooling water that enters the condenser at 18°C at a rate of 0.25 kg/ s and leaves at 26°C.
Calculate overall heat transfer coefficient (U) of material mild steel for a heat transfer from hot water to air at ambient temperature where thinkness is 1.5 mm (avg temp of hot water is 75C and air is 56C) not by using Q = U A log mean temperature ..
Air exerts a pressure of 900KPa within a 0.45 cubic meter container of fixed volume. It is cooled such that the pressure falls to 3.25bar. The temperature of the air is then measured and was found to be 285C. Determine the mass of the air, the initia..
The tank cover is airtight, and the pressure above the water surface is 2 atm gage. The system is at sea level. Determine the max height to which the water stream could rise.
Consider the number of significant figures in the standard deviations cited in the table. [s the number of digits justified in each case') Support your answer with statistical calculations.
Understand mechanism of hardenability in steels by Jominy-end quench method - Samples have been heat treated using the following conditions: Austenitizing at about 900oC for 30 minutes, water spray from one end until the whole samples cooled down to ..
two cylinders are filled with liquid water ? 1000 kgm3 and connected by a line with a closed valve. a has 100 kg and b
a balloon behaves so the pressure is p c2v13 c2 100 kpam. the balloon is blown up with air from a starting volume of
Show that the thrust developed by a stationary rocket motor is F = rho*A*U^2 + A(p- p_atm) where p_atm is the atmospheric pressure, and p, rho, A, and U are, respectively, the pressure, density, area, and velocity of the fluid at the nozzle exit.
