A die is tossed twice find the probability that;
a. A one and six occurs.
b. At least one three occurs.
c. Both numbers are the same.
A pipe of 6.5 cm outside diameter is covered with 5 cm (thickness) of asbestos layer
(conductivity = 0.12) and 4 cm (thickness) layer of cork (conductivity = 0.03). If the
temperature of outer surface of the pipe is 150 0 C and the temperature of the outer surface of
the cork is 35 0 C. Calculate the heat loss in W/m 0 C.
What is the effect of time constant on the response of a circuit?
Find the impulse response h[n] for a causal LTI discrete-time systems satisfying the given difference equations and indicate whether the system is a FIR or an IIR system.
y[n] - 1/2 * y * [n - 2] = 2x * [n] - x[n - 2]
From the given cross section of an earthworks between A ( 20+200) and B (20+220) assuming
both have same slope and width of base. All measurements are in meters.
a. Compute the width of the base.
b. Compute the value of cut at station B if it has an area of 16.82 m2
c. Compute the volume between A and B with prismoidal correction
What makes axial flow fans more suitable for applications where large flow rates of air are to be handled. What new developments have taken place in the design of fans for air conditioning applications?
What is Engineering mechanic
determine the saturated temperature, saturated pressure and enthalpy for water at specific volume of saturated vapor at 10.02 m³/kg
Two kg of air in a closed system undergoes an isothermal process from 606 kPa and 200°C to 75 kPa. The heat transfer (expressed to ZERO decimal places) during the process is in kJ:
From the tables (air is assumed as ideal gas based on given conditions), the gas constant for air: R = 0.2870 kJ/kg·K.
