Answer #1

For water, density and viscosity decreases with increase in temperature.

For air, density decreases but viscosity increases with increase in temperature.

Percentage change is calculated with respect to lower value.

Please ask any further query in comment section.

Question 6 Gauge pressure is the difference between actual pressure (or absolute pressure) at a point of a system, and atmospheric pressure. Essentially it is pressure within a fluid, either liquid or a gas, at depth. Car tyre pressure is reported as gauge pressure, since the compressed air inside the tyre is a fluid, and is the difference between actual pressure of the tyre and atmospheric pressure. Answer the following questions: a) What is the absolute pressure in the tyre,...

Given: The viscosity is negligible. Atmospheric pressure is 101300 Pa. Water flows at speed of 5.9 m/s through a horizontal pipe of diameter 3.3 cm. The gauge pressure P1 of the water in the pipe is 1.6 atm. A short segment of the pipe is constricted to a smaller diameter of 2.4 cm. What is the gauge pressure of the water flowing through the constricted segment? Answer in units of atm.
