On a part-time job, you are asked to bring a cylindrical iron rod of density 7800 kg/m3, length 78.4 cm and diameter 2.30 cm from a storage room to a machinist. Calculate the weight of the rod, w. Assume the free-fall acceleration is g

What does this circuit do? T is the clock All flip flops are D-Flip-Flop What is the function of the circuit if Dser is '1' always and flip flops are initialized to '001'.

Two tanks (Tank A and Tank B) are separated by a partition. Initially Tank A contains 2 kg of steam at 1 MPa and 300°C while Tank B contains 3 kg of saturated liquid-vapor mixture at 150°C with a vapor mass fraction of 50 percent.
