A 20 ft3 container has two partitions. Partition A, whose volume is 11 ft3, contains six Ibm of air at 85 °F. Partition B, on the other part, is evacuated. The air expands freely to fill the entire container, and comes to rest with temperature of 90 °F. At this final state, a pressure gauge connected to the vessel reads 25 psi, and the atmospheric pressure is 14.7 psi. What was the initial pressure in kPa?

The viscosity of liquids can be measured through the use of a rotating cylinder viscometer of the type illustrated in Fig. P1.3. In this device the outer cylinder is fixed and the inner cylinder is rotated with an angular velocity w. The torque T, required to develop w is measured and the viscosity is calculated from these two measurements. Develop an equation relating u, w, T, e, Ro and Ri. Neglect end effects and assume the velocity distribution in the gap is linear.…
The pressure a car tire measured to be 200 kPa (gauge) before a trip to Welkom from Bloemfontein. On arrival at Welkon, the mesured presure was 219 kPa (gauge) after the trip. The atmospheric pressure of both places are given as 85 kPa. If the temperature of air in the tire before the trip is 16 ° C, determine the air temperature after the trip ( ° C to 2 decimal place). NB: the degree sign may not be included in the answer unit.=
