A mass of 5 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder device at 125 kPa. Initially, 2 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 20 percent.
Determine:
(a) the initial and final temperatures,
(b) the mass of liquid water when the piston first start moving

Consider the following schema:Suppliers (sid: integer, sname: varchar, address: varchar) Parts (pid: integer, pname: varchar, color: varchar) Catalog (sid: integer, pid: integer, cost: real) Where sid is the supplier's id (primary key in Suppliers), pid is the part's id (primary key in Parts), and sid together with pid is the primary key of Catalog. The Catalog relation lists the prices charged for parts by Suppliers. A) Write the following queries using relational algebra:5 Find the sids of suppliers who supply every part6. Find the sids of suppliers who supply every red part7. Find the sids of suppliers who supply every red or green part. 8. Find the sids of suppliers who supply every red part or supply every green part

A rigid tank having 21.225 m^3 volume contains air having density of 1.829 kg/m^3 Air is supplied to the tank from a high-pressure supply line via a valve connection, until the air density reaches to 5.007 kg/m^3. This procedure has taken 56.101 minutes. Calculate the mass flow rate of the air supplied from high - pressure line to the tank. Enter your result in kg/s, and use 3 decimals.

A researcher wants to determine if lead levels are different between the top of a glass of water and the bottom of a glass of water. Many samples of water are taken. From half, the lead level at the top is measured and from half, the lead level at the bottom is measured. Would this be a valid matched pair test?
a. No, as the lead levels cannot be accurately measured
b. No, as the measurements of top and bottom should be from the same glass
c. Yes, as long as there are an equal number of glasses in each group
d. Yes, as long as they are all from the same faucet

Experimental data indicate that in a region downstream of a given louvered supply vent the velocity of the emitted air is defined by τ = 0.18τo/x where τ and x are expressed in m/s and meters, respectively, and τo is the initial discharge velocity of the air. For τo 3.6 m/s. Determine:
a. The acceleration of the air at x = 2m.
b. The time required for the air to flow from x=1 to x = 3m.
